PPH-500A Probest Factory High Quality Ph Sensor Electrode Probe for Tap Drinking Water

PPH-500A Digital pH sensor
 Measurement Principle
The pH sensor uses a composite electrode in which a glass indicating electrode and a reference electrode are combined to measure the pH of the water.
 Features
 Power supply and output isolation design to ensure electrical safety.
 Power supply and communication chip built-in protection circuit, strong anti-interference ability.
 With a comprehensive protection circuit design, it can work reliably without additional equipment.
 The circuit part is designed inside the electrode, the environment is well tolerated, and the installation operation is easier.
 RS-485 transmission interface, MODBUS-RTU communication protocol, two-way communication, can receive remote commands.
 Output more electrode diagnostic information, more intelligent.
 Internal integrated memory, memory calibration and setting information can be memorized.
