MB-300-ION-2 Nitrate Concentration Transmitter
ION-7120 Nitrate Concentration Transmitter
Application area ：
The ion selective sensor is installed directly in the activated sludge tank of the sewage treatmen 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 formonitoring the concentration of Nitrate concentratio： sSludge tank sThe primary settling tank outlet
Instructions Color
| Features： |
l Without sample pretreatment, direct Nitrate concentratio measurement l Chloride ion measurement is optional, can also compensate for the high concentration of interference l Range:0.1-1000 mg/l NO3-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 |
