Analog pH Meter Pro
The Analog pH Meter Pro is specially designed for Arduino controllers. It use an industry electrode and has built-in simple, convenient ,practical connection and long life (up to 1 year), which makes it very suitable for long term online monitoring. 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, then plug the PH2.0 interface into the analog input port of any Arduino controller. If programmed , you will get the pH value easily.
This industrial pH electrode is made of sensitive glass membrane with low impedance. It can be used in a variety of PH measurements with fast response and excellent thermal stability.
