Operation
1. Open the electrode(automate turn-on the power supply).Remove the protective cap.
2. First rinse the electrode with distilled water, and suck it withfilter paper.
3. Immerse the PH meter electrode in the solution to be tested.Stir gently and wait about one minute. Read display value.
4. After use, rinse the electrode with water to minimize contamination. Replace the protective cap. Fur the electrode(automate shut-off the power supply).
PH Calibration (Not included)
1. Immerse the electrode in PH 6.86(under the temperature of 25℃)standard buffer solution of phosphate, and turn it gently.
2. Regulate the trimmer"STAND"with a screwdriver until buffer solution value corresponding to the measurement temperature is obtained. (This instrument have automatic temperature compensation, compensation to 25℃).
3. After cleaning and wiping the electrode, Immerse the electrode in PH4. 00 or PH9. 18 buffer solution. After about two minutes until the buffer solution value corresponding to the measurement temperature is obtained.
