Calibration: washed with pure water and dried, and the electrode during sapin pH7.00 buffer solution, and then stirred and allowed to stand, then shame warmth, press the button for 2 seconds, then placed on a digital marker "CRL" is displayed, the digital "7.0 "pH then appeared, and a few seconds after calibration is complete.
Measurement: After cleaning with pure water and dried, and the electrode during sapin pH7.00 buffer solution, allowed to stand after stirring, after the numerical value read warmth.
Electrode cap on the use of electrode and dry, cleaning with pure water.
■ Notes
1. The sponge in the electrode, and keep the moisture, and maintains electrode active
2. Electrode cleaning method: After washing the emulsion proceeds brush soapy water, rinsing with pure water for several hours after the calibration.
3. Ph electrode replacing method: Acquired the electrode needles turning 7-8 times a take-out transition, again fixed to the rotation after the insertion of new electrode.
