GEC-pH485 digital sensor is a new generation of intelligent water quality detection digital sensor independently developed by our company. Without the host, directly measure the pH value and temperature value in the solution , and send output 4-20mA signal to the back-end equipment. It can also be connected to RS485 interface, and connected to the computer through MODBUS protocol for monitoring and recording.
