Product Details
Online Ammonia Nitrogen Automatic Analyzer Sensor RS-485 for
aquaculture
Online ammonia nitrogen sensor, no reagents required, green and
non-polluting, can be monitored online in real time. Integrated
ammonium, potassium (optional), pH and reference electrodes
automatically compensate for potassium (optional), pH and
temperature in water. It can be directly put into installation,
which is more economical, environmentally friendly and convenient
than traditional ammonia nitrogen analyzer. The sensor has a
self-cleaning brush that prevents microbial adhesion, resulting in
longer maintenance intervals and excellent reliability. It adopts
RS485 output and supports Modbus for easy integration.
Features
*Digital sensor, RS-485 output, support MODBUS;
*No reagents, no pollution, more economical and environmentally
friendly;
*The principle of ion selective electrode; *Automatically
compensates for pH and temperature in water;
*Electrodes can be replaced individually.
Sensor maintenance
1)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.
2)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.
3)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.
