SPS-pH Water Quality Sensor

The pH sensor uses a composite electrode composed of a glass indicator electrode and a reference electrode to measure the pH value of water. The potential of the internal reference electrode in the glass electrode is constant and has nothing to do with the pH of the solution to be tested. When the glass bulb is immersed in the solution to be tested with a changing H+ concentration, the difference between the stable potential of the reference electrode and the potential generated by the glass bulb will be read by the voltmeter and used as the measurement result.
The pH sensor supports RS485 output mode and miniaturizes the transmitter module. It is separated from the pH electrode by a separate design. The pH sensor’s maintenance only requires replacing the pH glass electrode part, effectively reducing costs. pH sensors are widely used in drinking water, pipe network water, surface water, and various types of sewage.
