PH Sensor for Water and Wastewater Monitoring

This is an Analog PH Meter kit with the industrial real-time online electrode, specially designed for Arduino and other microcontrollers, it uses an industry electrode and has a built-in simple convenient, practical connection and long life up to 1 year, which makes it very suitable for long-term online monitoring, TO use it m just connect the PH sensor with BND connector, then plug their PH interface into the analog input port of any microcontroller or Arduino controller, if programmed you will get the pH value easily.
The most common method of measuring pH is to use an electrochemical pH sensor. Combination pH sensors are a type of electrochemical pH sensor that features both a measuring electrode and a reference electrode. The measuring electrode detects changes in the pH value while the reference provides a stable signal for comparison. A high impedance device, known as a pH meter, is used to display the millivolt signal in pH units.
