Features

FEATURES


●  signal output: RS-485 ( Modbus/RTU protocol ).

● Conveniently connected to third-party devices such as PLC, DCS, industrial control computers, general controllers, paperless recording instruments or touch screens.

● Dual high-impedance differential amplifiers, strong anti-interference and fast response.

● ORP probe, the internal reference liquid seeps out from the microporous salt bridge extremely slowly under a pressure of at least 100KPa (1Bar), and its positive seepage lasts for more than 20 months. Such a reference system is very stable and the electrode life is doubled compared to ordinary industrial electrodes.

● Easy to install: 3/4NPT pipe thread, easy for submersible installation or installation in pipes and tanks.

●  IP68 Protection rating.
