PH Meter 4-20mA Output PH Composite Electrode Online Monitoring Water pH Probe Sensor
Product instruction
1.Calibration and setting password protection
2.16 × 2 LCD screen with backlit display
3. Technical parameters can be set on-site using buttons
4. High stability and precision; Measurable pH, ORP, and temperature
5. Super strong anti-interference circuit design, can be installed and used in strong interference sites. After power failure, the set parameters and calibration data will not be lost. It has manual setting/automatic temperature compensation process temperature and calibration temperature. When the temperature electrode is damaged, it will be converted from automatic temperature compensation to manual temperature compensation, and the test data can be verified online
6. Multiple output modes (relay, 4.00~20.00mA)
7. Suitable for industries such as water quality treatment, thermal power, metallurgy, pharmaceuticals, environmental protection, food, tap water, chemical industry, etc
