MEASUREMENT Rinse the electrode tip with distilled water, immerse it 4 cm (1½") in the sample and stir gently for a few seconds. For a faster response and to avoid cross contamination of the samples, rinse the electrode tip with the solution to be tested, before taking any measurements. STORAGE PROCEDURE To minimize clogging and ensure a quick response time, the glass bulb and the junction should always be kept moist. When not in use, store it with a few drops of HI 70300 storage solution in the protective cap. NEVER STORE THE ELECTRODE IN DISTILLED OR DEIONIZED WATER. PERIODIC MAINTENANCE Inspect electrode and cable. No cracks should be seen on the electrode stem or bulb. If any scratches or cracks are present, replace the electrode. Connectors must be perfectly clean and dry. For refillable electrodes: Refill the electrode with fresh electrolyte (see the electrode's specifications to select the correct refilling solution). Allow the electrode to stand upright for 1 hour. CLEANING PROCEDURE Soak in Hanna HI 7061 General Cleaning · General Solution for approximately ½ hour. · Protein Soak in Hanna HI 7073 Protein Cleaning Solution for 15 min. [. . . ] Measurements can be affected by the recharging process. · Only recharge the batteries in a non hazardous area, when using the HI 710044 inductive recharger. 14 19 m V CALIBRATION HI 9126 has been precalibrated for mV range at the factory. For optimum accuracy, it is recommended to recalibrate the meter for mV readings at least once a year. Contact your Dealer or the nearest Hanna Customer Service Center for more information. p H BUFFER TEMPERATURE DEPENDENCE The temperature has an effect on pH. [. . . ]
