PPH-500B China Probest Factory High Quality Ph Sensor Electrode Probe Water Online Analyzer

PPH-500A Digital pH sensor
Measurement Principle
PH-500B is a digital PH sensor using RS485 communication interface and standard Modbus protocol. It adopts stainless steel corrosion-resistant casing, IP68 protection grade, built-in PT1000 temperature sensitive resistor and compensation algorithm, which has the advantages of high precision, long life and small drift, and is suitable for various harsh working environments.

Features
 Built-in PT-1000 temp. sensitive resistor, effective temperature compensation.
 Support replacement of electrode cores to reduce operation and maintenance costs.
 Industrial grade composite pH electrode, suitable for harsh working environment.
 Corrosion-resistant shell, waterproof grade IP68, can work underwater for a long time.
 RS485 communication interface, standard Modbus protocol, easy to integrate.
 Standard digital signal output, can achieve integration and networking with other equipment without controller.
 Built-in self-diagnosis function to ensure the accuracy of data.
 Digital sensor, high anti-jamming capacity and far transmission distance.
 Plug-and-play sensor, quick and easy installation.
 Sensor power supply positive and negative reverse connection protection.
 Sensor RS485 A/B terminal is connected to the power supply protection.
 With time display, data storage and historical data viewing function.
 Optional data wireless transmission module
