The SEN0161 Gravity pH Sensor Kit is specially designed for Arduino controllers and has a 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 BND connector, and plug the PH2.0 interface into the analog input port of any Arduino controller. If pre-programmed, you will get the pH value easily. Comes in compact plastic box with foams for better mobile storage
Note: If you want to measure the pH value of other solutions, you must wash the pH electrode first!
- According to the linear characteristics of the pH electrode itself, after the above calibration, you can directly measure the pH value of the alkaline solution, but if you want to get better accuracy, you can recalibrate it. Alkaline calibration uses the standard solution whose pH value is 9.18. Also, adjust the gain potential device, let the value stabilize at around 9.18. After this calibration, you can measure the pH value of the alkaline solution.
