Products Description
Yige independently develops electronic online monitoring of PH/0RP values, which are transmitted remotely to the monitoring room through RS485 or current transmission for recording and storage.
PH/ORP tester is one of the intelligent online chemical analysis instruments, widely used for continuous monitoring of pH or ORP values and temperature in solutions such as thermal power, chemical fertilizers, metallurgy, environmental protection, pharmaceuticals, biochemistry, food, and tap water.
Continuous monitoring data can be remotely transmitted and recorded through a transmission output connected to a recorder. It can also be connected to an RS485 interface and conveniently connected to a computer through the MODBUS-RTU protocol for monitoring and recording.
