MB-300-ION-1 Ammonia Concentration Transmitter
ION-7110 Ammonia Concentration Transmitter
Application area ：
The ion selective sensor is installed directly in the activated sludge tank of the sewage treatment plant,Without any sample pretreatment or sample transfer.The whole measuring system includes sensors and transmitters:Sensor containing electrode,Transmitter includes display and operating unit.Sensor for monitoring the concentration of ammonia nitrogen： sSludge tank sThe primary settling tank outlet.
Instructions Color
| Features： |
l Without sample pretreatment, direct ammonia nitrogen measurement l Potassium ion measurement is optional, can also compensate for the high concentration of interference l pH measurement and compensation l Without reagents, the use of low cost l Range:0.1-1000 mg/l NH4-N l Direct installation in the pool, without liquid collector or sample transfer pump l Compressed air cleaning optional, low maintenance cost l Every 6 months to replace the coated cap, effectively extend the life of the electrode |
