If the meter is OFF, detach the electrode from the meter before immersing the electrode in the storage solution. Reference Filling Hole Reference Filling Hole Sensitive Wire Reference Wire Reference Junction Glass Bulb Plastic Body pH Electrode Reference Wire Sensitive Wire Reference Junction Glass Bulb Glass Body pH Electrode For instance, if the buffer temperature is 25 C, the display should show pH 4. 01, 7. 01 or 10. 01 at pH 4, 7 or 10 buffers, respectively. At 20 C, the display should show pH 4. 00, 7. 03 or 10. 06. The meter reading at 50 C will then be 4. 06, 6. 98 or 9. 82. Reference Wire Reference Junction Platinum or Gold tip Reference Wire Reference Junction Platinum or Gold tip Glass Body ORP Electrode Plastic Body ORP Electrode PREPARATION Remove the protective cap. DO NOT BE ALARMED IF SALT DEPOSITS ARE PRESENT. This is normal with electrodes and they will disappear when rinsed with water. During transport tiny bubbles of air may form inside the glass bulb affecting proper functioning of the electrode. These bubbles can be removed by "shaking down" the electrode as you would do with a glass thermometer. If the bulb and/or junction is dry, soak the electrode in HI 70300 or HI 80300 Storage Solution for at least one hour. 10 11 For refillable electrodes: If the filling solution (electrolyte) is more than 2½ cm (1") below the fill hole, add HI 7082 or HI 8082 3. 5M KCl Electrolyte Solution for double junction or HI 7071 or HI 8071 3. 5M KCl+AgCl Electrolyte Solution for single junction electrodes. For a faster response, unscrew the fill hole screw during measurements. for single junction or HI 7082 or HI 8082 for double junction electrodes). Allow the electrode to stand upright for 1 hour. Follow the Storage Procedure above. CLEANING PROCEDURE Soak in Hanna HI 7061 or HI 8061 General Cleaning Solution for approximately ½ hour. Removal of films, dirt or deposits on the membrane/junction: Soak in Hanna HI 7073 or HI 8073 Protein Cleaning - Protein Solution for 15 minutes. - Inorganic Soak in Hanna HI 7074 or HI 8074 Inorganic Cleaning Solution for 15 minutes. - Oil/grease Rinse with Hanna HI 7077 or HI 8077 Oil and Fat Cleaning Solution. IMPORTANT: After performing any of the cleaning procedures rinse the electrode thoroughly with distilled water, refill the reference chamber with fresh electrolyte (not necessary for gel-filled electrodes) and soak the electrode in HI 70300 or HI 80300 Storage Solution for at least 1 hour before taking measurements. TROUBLESHOOTING Evaluate your electrode performance based on the following. · Noise (Readings fluctuate up and down) could be due to: ­ Clogged/Dirty Junction: Refer to the Cleaning Procedure above. ­ Loss of shielding due to low electrolyte level (in refillable electrodes only): refill with fresh HI 7071 or HI 8071 for single junction or HI 7082 or HI 8082 for double junction electrodes. · Dry Membrane/Junction: Soak in HI 70300 or HI 80300 Storage Solution for at least 1 hour. · Drifting: Soak the electrode tip in warm (approx. 50-60 C) Hanna HI 7082 or HI 8082 Solutions for one hour and rinse the tip with distilled water.
