Detail HI98118 Waterproof PH Tester
pH Measurement and Calibration • Make sure the meter has been calibrated before use. • If the electrode is dry, soak it in HI70300 storage solution for 30 minutes to reactivate it. • Submerge the electrode in the sample to be tested while stirring it gently. Wait until the Stability Indicator on the LCD disappears. • The LCD displays the pH value (automatically compensated for temperature) on the primary LCD, while the secondary LCD displays the sample temperature. • If measurements are taken in different samples successively, rinse the electrode tip thoroughly to eliminate cross-contamination. After cleaning, rinse the electrode tip with some deionized water and some of the sample to be measured. pH calibration • Enter calibration mode while in pH measurement mode. • Place the electrode into the first calibration buffer. If performing a two-point calibration, use pH 7.01 buffer first. • The meter will enter the calibration mode, displaying “pH 7.01 USE”. Single-point calibration 1. Place the electrode in buffer pH 7.01, 4.01 or 10.01 buffer. The meter will automatically recognize the buffer value. 2. If the buffer is recognized “REC“ is displayed until the reading is stable and the calibration is accepted. 3. If the buffer is not recognized the pH electrode is not immersed in solution, or the reading is out of the accepted range “---- Err“ is displayed.
