HI7061L is a general purpose cleaning solution for use with pH and ORP electrode that can be used for a variety of applications. pH electrodes become dirty with use and can produce inaccurate results. Use our General Purpose pH Electrode Cleaning Solution to prolong the life of your electrode and ensure accurate readings. Specially formulated for cleaning pH and ORP electrodes Clearly marked expiration date and lot number for traceability. Air-tight seal to ensure the quality of the solution The most common cause for pH measurement inaccuracies is an unclean or improperly cleaned electrode. This is very important to note, because during calibration, the instrument assumes that the electrode is clean and that the standardization curve created during the calibration process will remain a valid reference until the next calibration. pH meters on the market today will allow an offset voltage of approximately ±60 mV. The deviation from 0 mV is not unusual but ideally should be no greater than ±30 mV. The calibration process compensates for the change in offset voltage. If the mV offset continues to deviate and the meter is calibrated with a dirty electrode then inaccurate readings will result. Cleaning is a fast and effective routine that should be performed on a regular basis as a preventative measure against using a dirty electrode and to ensure that the junction is not clogged. By simply immersing the electrode in the HI7061L cleaning solution for 15 to 20 minutes will dissolve any mineral deposits or other coatings.   Air tight bottle with tamper-proof seal Ensures quality and freshness of solution Each bottle marked with lot number and expiration date.

edge® digital wine pH meter kit delivers precision while offering simplicity and versatility in a sleek design. Upgrade to the Hanna edge® wine pH kit for professional winemakers. The HI2020W allows you to add a conductivity probe and a dissolved oxygen probe to give you full versatility. Fast results, ultra-accurate, hassle-free analysis. Complete meter kit for measuring pH in wine. CAL Check™ feature ensures the accuracy of the meter. Great for professional and home winemakers. The Importance of pH in Wine Making The pH of wine is important to determine because it will affect the quality of the final product in terms of taste, color, oxidation, chemical stability and other factors. Generally in winemaking, the higher the pH reading, the lower amount of acidity in the wine. Three important factors in determining the pH of wine include the ratio of malic acid to tartaric acid, the amount of potassium, and the total amount of acid present.   The edge HI2020W wine pH meter kit includes all the necessary supplies to determine the pH of wine must and juice accurately. The meter supplied with the HI2020W is the multiparameter edge, HI2020. The HI2020 is an advanced meter that is rich in features including using digital electrodes that can be swapped out anytime to switch to a different parameter, built in rechargeable battery, two USB ports, datalogging, automatic calibration, GLP (good laboratory practice) data for last calibrations, and Hanna’s exclusive calibration check feature that will alert the user to potential problems during calibration including when to clean the electrode and when the buffer might be contaminated. The HI2020 is a versatile pH meter for winemaking that be used as a benchtop, portable and even a wall mount to conserve space. The HI2020 is one of the most advanced meters available but  the most important aspect in measuring pH is having the correct sensor for the application.   The HI2020W wine kit is packaged with the HI10480 (MT620Z) in place of the normally supplied HI11310. The HI10480 is a specially designed pH electrode that is resistant to clogging to the solids found in grape juice and must. This double junction, refillable pH electrode has a unique ground glass junction and PTFE sleeve to provide unsurpassed performance for the wine industry.  A standard pH electrode will have a ceramic junction that can be easily clogged by solids. When this happens the pH readings will be erratic and drift over time before stabilizing on the actual pH value of the wine sample. The HI10480 with CPS technology will prevent the junction from clogging. The HI10480 is a digital electrode that when used with the edge HI2020 will change the default buffer set from pH 4.01and  7.01 to  pH 3.00 and 7.01.   The edge HI2020W (MT620) wine pH meter (kit) includes the HI180-1 compact magnetic mini-stirrer. The use of a magnetic stirrer allows for proper mixing and the sample to be homogenous in consistency and temperature. The stirring of the sample also helps speed up the response time of a sensor in achieving a stable reading.    The edge HI2020W wine pH kit also includes all the solutions for calibration and maintenance. In order to ensure the highest of accuracy in measurement it is important to bracket the calibration buffers around the expected reading. Since the pH of wine is less than pH 4.01 it is important to calibrate at a lower pH value. For calibration the kit includes the HI5003 (MT611) pH 3.00 and the HI5007 pH 7.01 technical calibration buffer. Each bottle of buffer NIST traceable is supplied with a certificate of analysis that includes lot number, expiration date and reference materials used in production.    For maintenance the The HI70635L cleaning solution for wine deposits and the HI70300L (MT631)electrode storage solution. When the “clean electrode” message is displayed during the calibration of the HI2020 edge or there is a poor probe condition (i.e. less than 30%) then soak the HI10480 in the cleaning solution for 15 minutes to clean any deposits from the glass surface. After cleaning the probe should be rinsed with purified water and then allowed to soak in the storage solution for 2-3 hours. The electrode storage solution is also used when the electrode is not in use. Either place a small amount into the storage cap or into a beaker in order to maintain a properly hydrated electrode.   Importance of maintaining a clean pH electrode The most common cause for pH measurement inaccuracies is an unclean or improperly cleaned electrode. This is very important to note, because during calibration, the instrument assumes that the electrode is clean and that the standardization curve created during the calibration process will remain a valid reference until the next calibration. pH meters on the market today will allow an offset voltage of approximately ±60 mV. The deviation from 0 mV is not unusual but ideally should be no greater than ±30 mV. The calibration process compensates for the change in offset voltage. If the mV offset continues to deviate and the meter is calibrated with a dirty electrode then inaccurate readings will result.   The Cleaning Solution Series ensures maximum efficiency and accuracy of your sensors when used for its designated application. Cleaning is a fast and effective routine that should be performed on a regular basis as a preventative measure against using a dirty electrode and to ensure that the junction is not clogged. Benchtop Portable, or Wall Mount versatile pH meter Swappable digital electrodes Built in rechargeable battery Two USB ports Automatic calibration,and data logging for GLP data Large easy to read display   NOTE: The shape of the stir plate may differ from what is shown in the example photo.

The HI1048B is a glass body, refillable, sleeve junction pH electrode with a BNC connector. This electrode features a double junction reference, Hanna's Clogging Prevention System (CPS) technology and spherical glass sensing bulb made with general purpose glass. This pH electrode is ideal for wine must and juice due to their high solids content that would clog a standard general purpose pH electrode. Clogging Prevention System (CPS™) Technology Refillable Electrode Double Junction Design Hanna Instruments offers a wide variety of pH electrodes that are designed for many different applications. The type of glass used for sensing pH, bulb shape, body material, type of junction, type of reference and electrolyte used are just some of the design considerations.   The HI1048B uses general purpose (GP) glass, spherical bulb, glass body, sleeve junction with CPS™ technology, double junction and is refillable with 3.5M KCl, making it ideal for wine must, juice, and other samples with a high solids content.   General Purpose Glass Formulation General Purpose (GP) glass, as the name implies, is a standard glass formulation that is used for general use. A pH electrode with GP glass will have a resistance of 100 megaohms at 25°C and is suited for measuring the pH of samples that are at ambient temperatures. The HI1048B is suitable to use with samples that measure from 0 to 80°C.   Spherical Glass Tip The spherical shaped tip design allows for a wide area of contact with the measured sample. This permits a faster electrode response with a higher degree of stability.   CPS Sleeve Junction Clogging Prevention System (CPS) technology is an innovation in for the improvement of pH measurements in samples that have a high solids content. Conventional pH electrodes use ceramic junctions that can clog quickly when used in samples that have a high solids content such as wine must or juice. When the junction is clogged, the electrode does not function. CPS technology utilizes the porousness of ground glass coupled with a PTFE sleeve to prevent clogging of the junction. The ground glass allows the proper flow of the liquid, while the PTFE sleeve repels solids. As a result, pH electrodes with CPS technology take up to 20 times longer to be fouled as compared to conventional electrodes.   Double Junction Reference A double junction electrode has an internal compartment surrounding the reference wire. Silver ions are present in the electrolyte of the internal compartment, which houses the Ag/AgCl reference wire; the electrolyte outside this compartment is silver free. The double junction design means that virtually no silver from the electrode enters the sample. This design allows measurement in applications where silver ions in the sample are undesirable or for samples that contain sulfides that can cause the silver to precipitates and clog the junction. The clogging of the junction will result in drifty and erratic readings.   Refillable The HI1048B is a refillable probe. Since it is a double junction pH electrode, the fill solution is the HI7082 3.5M KCl. This solution does not contain any silver as with single junction electrode fill solutions.   Glass Electrode Body The glass body is ideal for laboratory use. The glass is resistant to many harsh chemicals and is easily cleaned. The glass body also allows for a fast transfer of heat to the internal reference electrolyte. The mV generated by the reference cell is temperature dependent. The faster the equilibrium the steadier the reference potential.   BNC Connector The HI1048B has a BNC connector. This type of connector is universal in that it can be used on any pH meter that has a female BNC probe input. Other types of connectors include DIN, screw type, T-type, and 3.5mm to name a few. These types of connectors tend to be proprietary for a particular type of meter and are not interchangeable.   Single Junction Versus Double Junction pH Electrodes Conventional electrodes are normally single junction. As depicted by the figure above, these electrodes have only a single junction between the internal reference wire and the external solution. Under adverse conditions, such as high pressure, high temperature, highly acidic or alkaline solutions, the positive flow of the electrolyte through the junction is often reversed resulting in the ingress of sample solution into the reference compartment. If this is left unchecked, the reference electrode can become contaminated, leading to complete electrode failure. Another potential problem with single junction electrodes is the clogging of the junction due to silver chloride (AgCl) precipitation. Silver can be easily precipitate in samples that contain Tris buffer or heavy metals. When the electrolyte solution makes contact with the sample, some AgCl will precipitate on the external face of the junction. The result is drifty readings obtained from the sensor.   Hanna’s double junction system, as the name implies, has two junctions, only one of which is in contact with the sample as shown in the figure. Under adverse conditions, the same tendency of sample ingress is evident. However, as the reference electrode system is separated physically from the intermediate electrolyte area, the contamination of the electrode is minimized. The likelihood of clogging of the junction is also reduced with a double junction electrode since the outer reference cell uses a fill solution that is “silver-free”. Since there is no silver present, there is no precipitate forming to clog the junction. Able to measure samples 0 - 80C Glass body, refillable sleeve junction PH electrode with a BNC connector Features a double junction reference with Hanna's Clogging Prevention System (CPS) technology and spherical glass sensing bulb made with general purpose glass Ideal for wine must and juice due to high solid content that would clog a standard general purpose PH Electrode

Internal clock date to keep track of different time-dependent functions (calibration, timestamp,calibration time out). 3 feet probe cables for extra flexibility when testing. Care and Use pH meters usually start performing poorly because of problems with the probe. The two parts of the pH probe that cause problems are the glass sensing bulb and the reference junction. Sensing Bulb The glass bulb loses sensitivity with use and will eventually fail. This is true of all pH probes. Reference Junction The reference junction is a small hole that allows the meter to compare the sample to a reference. The reading is generated based on the electrical difference between the sample and reference. If the junction hole gets clogged, the pH electrode will no longer function. You can extend the life of your pH electrode in the following ways. Storage To minimize clogging the pH probe needs to be kept hydrated. Long periods of dry storage will damage the sensitivity of the probe. Allowing the probe to dry out may also result in the junction hole getting clogged. Storing in pH probe storage solution or pH calibration buffers will help address both these issues. Do not store in tap water and DI water. This will damage the sensitivity of the probe. The best way to store the probe is with the probe's cap filled with storage solution or calibration buffer and the cap tightened to prevent leakage. It is also recommended that to store the electrode upright to further reduce the potential for leakage. Cleaning and Maitenance Residue from the sample can impact the sensitivity of the sensing bulb and clog the junction. This is especially true if the sample has a lot of organic material. We recommend regularly soaking your electrode in cleaning solution. Also: Inspect the electotrode for damage or scratches, if present replace the electrode. Inspect the cable.  The connection cable and insulation must be intact. Connectors should be clean and dry. Rinse off salt deposits with water or DI water. Calibration The pH sensing bulbs become less sensitive over time so make sure that you are calibrating regularly to keep your PRO Plus pH meter accurate.

The HI700635P is a highly effective cleaning solution that is specially formulated for use with pH electrodes that become coated with wine juice and must deposits. Electrodes can become dirty from use and will produce inaccurate results even as they read correctly in a pH buffer. Hanna's cleaning solutions eliminate impurities and residues that are left on electrode surfaces when immersed in samples during measurement and stored incorrectly. Hanna suggests cleaning the bulb and junction of your electrode on a regular basis to ensure that the probe is always clean and prevent any clogging of the junction. Each sachet has the lot number and expiration date stamped on it and is made of light block foil ensuring freshness each time one is opened. Hanna's line of cleaning solutions have been specially formulated to have an expiration of 5 years from the date of manufacture for an unopened sachet. Specially formulated cleaning solution to remove wine deposits from a pH electrode Convenient, one-time use sachets ensure freshness of solution The most common cause for pH measurement inaccuracies is an unclean or improperly cleaned electrode. This is very important to note, because during calibration, the instrument assumes that the electrode is clean and that the standardization curve created during the calibration process will remain a valid reference until the next calibration. pH meters on the market today will allow an offset voltage of approximately ±60 mV. The deviation from 0 mV is not unusual but ideally should be no greater than ±30 mV. The calibration process compensates for the change in offset voltage. If the mV offset continues to deviate and the meter is calibrated with a dirty electrode then inaccurate readings will result.   The Cleaning Solution Series ensures maximum efficiency and accuracy of your sensors when used for it’s designated application. Cleaning is a fast and effective routine that should be performed on a regular basis as a preventative measure against using a dirty electrode and to ensure that the junction is not clogged.

This information is automatically retrieved by edge® once the electrode is plugged in. The ability to transfer information allows for hot-swapping of probes without having to recalibrate. All pH measurements are performed within the electrode and transferred digitally to the meter. This overcomes any noise issues associated with the traditional high impedance analog measuring system. Electrical noise can be generated from a built-in temperature sensor and while working in a humid environment.   Spherical Glass Tip The spherical shaped tip design allows for a wide area of contact with the measured sample. This permits a faster electrode response with a higher degree of stability.  The HI10480 utilizes a low temperature (LT) glass formulation that has a resistance of around 50 megaohms at 25°C. As the temperature of the glass decreases in the sample, the resistance of the LT glass will approach that of GP glass. If using GP glass, the resistance would increase above the optimum range, resulting in increased impedance and ultimately affecting the measurement. The HI10480 is suitable to use with samples that measure from 0 to 80°C.   CPS Sleeve Junction CPS™ (Clogging Prevention System) is an innovation in electrode technology. Conventional pH electrodes use ceramic junctions that clog quickly when used in wine. When the junction is clogged, the electrode does not function. CPS™ technology utilizes the porousness of ground glass coupled with a PTFE sleeve to prevent clogging of the junction. The ground glass allows proper flow of the liquid, while the PTFE sleeve repels dirt. As a result, pH electrodes with CPS™ stay fresh up to 20 times longer than conventional electrodes.   Double Junction Reference A double junction electrode has an internal compartment surrounding the reference wire. Silver ions are present in the electrolyte of the internal compartment, which houses the Ag/AgCl reference wire; the electrolyte outside this compartment is silver free. The double junction design means that virtually no silver from the electrode enters the sample. This design allows measurement in applications where silver ions in the sample are undesirable or silver precipitates on the junction are likely to form.   Glass Electrode Body The glass electrode body is suitable for a wide range of applications due to its chemical resistance. The glass electrode is compatible with many non-aqueous solvents and other aggressive chemicals. Glass is also resistant to many forms of radiation, such as ultraviolet radiation. Built in temperature sensor Application specific electrode for measuring pH in wine and must Built in microchip that stores sensor type, serial number, and calibration information Features a double junction reference with Clogging Prevention System (CPS) technology, a glass body, and a spHerical tip Probe features a 3.5mm connector designed exclusively to be used with Hanna Instruments edge Tablet Meters
