Industrial Online Ammonia Nitrogen Sensor Water Treatment Quality Monitoring Meter Ammonia Sensor Probe
Online Ammonia Nitrogen Analyzer adopts ion selective electrode, which has advantages of rapid reaction, low maintenance cost, real-time online measurement, etc. No reagent, green and pollution-free, automatic compensation for potassium ion (set value), pH and temperature in water. Can be input installed directly, compared with the traditional ammonia nitrogen analyzer, it’s more economical and environment-friendly, convenient and quickly. The sensor is equipped with a self-cleaning brush that prevents microbial adhering, resulting in a longer maintenance cycle and excellent reliability. Adopt RS485 output, support to Modbus, easy integration.
Sensor maintenance
- External surface of the sensor: Wash the external surface of the sensor with tap water. If debris remains, wipe it with a moist soft cloth.
- Check the cable of the sensor: The cable should not be tight during normal work, otherwise the internal wires of the cable will be easily broken and the sensor will not work properly.
- Sensor storage: When the sensor is not in use, you should fasten the black plastic cap and check whether the sponge inside is wet. If it is not wet enough, please add 3mol / L potassium chloride solution and let the electrode be stored in the solution with potassium chloride.
