Description

This is an analog pH meter with temperature compensation feature, specially designed for Arduino controllers and has built-in simple, convenient and practical connection and features. It has an LED which works as the Power Indicator, a BNC connector and PH2.0 sensor interface. To use it, just connect the pH sensor with BNC connector, and plug the PH2.0 interface into the Arduino/MCU analog input port.

*Note #1: In order to ensure the accuracy of the pH probe, you need to use the standard solution to calibrate it regularly. Generally, the period is about half a year. If you measure the dirty aqueous solution, you need to increase the frequency of calibration.

*Note #2: If you want to measure the pH value of other solution, you must wash the pH electrode first!
