Character & Application:
- Industrial online PH/ORP Monitoring and controlling instrument.
- Three-point calibration function, automatic identification of calibration liquid and the error calibration.
- High input impedance, the adaptation of various types of PH /ORP electrode.
- The upper limit and low limit alarm relay control output functions, alarm return difference setup by keyboard, to form automatic closed-loop control system is more flexible and convenient.
- Modbus RTU RS485 output.
