Product Details
Ammonia Nitrogen Sensor NH4-N Sensor For Sewage Treatment Plant
Online ammonia nitrogen sensor, using ion selective electrode
method to measure ammonia nitrogen concentration. The ammonium ion
selective electrode directly detects ammonium ions in the water
environment to determine the concentration of ammonia nitrogen. Use
a pH electrode as a reference electrode for better stability. The
ammonia nitrogen concentration is easily interfered by potassium
ions during the measurement process, and potassium ion compensation
is required.
The digital ammonia nitrogen sensor is an integrated sensor
composed of ammonium ion selective electrode, potassium ion
(optional), pH electrode and temperature electrode. These
parameters can mutually correct and compensate the measurement
value of ammonia nitrogen, and realize the measurement of multiple
parameters at the same time.
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.
