Nitrate and Ammonium armature with temperature measurement


Design according to the minimum requirements for measuring instruments used at 
waste water treatment plants defined by ATV (waste water association) in bulletin M256.  

Digital nitrate and ammonium sensor for installation of a nitrate and a ammonium 
replacement electrode, a reference electrode and a compensation electrode for 
potassium or chloride; for connection to the IQ SENSOR NET multiparameter 
measuring system; with integrated temperature sensor.

Equipped with the following features:

- Integrated lightning protection
- Sensor with integrated preamplifier for low impedance signal transmission
- Thermistor system for temperature compensation
- With screw / plug connector for connection of the SACIQ sensor connection cable
- For integration of reference electrode VARiONRef
- For two measuring electrodes and one compensation electrode
- With automatic compensation of interference ions
- Measuring range: 0.1 - 2,000 mg/l NH4-N; 0.1 - 1,000 mg/l NO3-N
- Compensation range: 1 - 1,000 mg/l K+ and CL-
- Conditions: 0C..40C, pH range: 4..8.5 pH 
- Use with automatic compressed air cleaning recommended 
(MIQ/CHV magnetic valve module or Cleaning Air Box as well as CH cleaning head
required for the systems 184 XT/ 2020 XT or DIQ/CHV for the system 182 )
