Audited Supplier
Yigeqi independently develops electronic online monitoring of PH/ORP values, which are transmitted to the monitoring room through RS485 or current transmitter for record preservation.
PH/ORP tester is one of the intelligent online chemical analysis instruments, which is widely used in continuous monitoring of PH value or ORP value and temperature in solutions such as thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemistry, food and tap water.
Continuous monitoring data is connected to the recorder through the transmitter output to achieve remote monitoring and recording, and can also be connected to the RS485 interface through the MODBUS-RTU protocol to easily connect to the computer for monitoring and recording.
