Features:

1. MCU is used to control the measurement process and digital filtering is used to improve the system reliability

2. Manual and automatic temperature compensation and digital temperature compensation technology are adopted to eliminate the non-linear factors of temperature compensation.

3. Two point calibration function of pH meter is optional

4. When calibration you only need to input the nominal value of buffer at 25 ℃, and the instrument will automatically recognize and compensates the temperature.

5. Auto lock mode: stable indication lock automatically will be displayed.

6. Can store 99 pH values

7. Data will not lose even when power is cut off.

8. Power display function.

9. The slope is shown and the quality of the electrode can be judged accordingly.
