DPH-160 online ORP digital sensor/transmitter
(RS-485/ModbusRTU)
What you measure is what you get, with digital sensor technology, measurements are no longer erratic.
Powerful Modebus RTU/RS-485 transmission method, rich data carrying, accurate measurement of acid-base changes!
● RS-485 ( Modbus/RTU protocol ) signal output.
● 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.
