Digital ISE sensor AmmoLyt® for ammonium
Ammonium measurement directly in the medium without sample preparation and sample transfer. Measurement of centrate and other process waters up to 2,000 mg/l NH4-N

Measuring method: Electrochemical
Appropriate Electrode: Reference electrode VARiON® Ref, Measuring electrode VARiON®Plus NO3, Compensation electrode VARiON®Plus Cl
Measuring range/Resolution
NH4-N: 1 ... 2,000 mg/l / 1 mg/l; 0.1 ... 100 mg/l / 0.1 mg/l
NH4+: 1 ... 2,580 mg/l / 1 mg/l; 0.1 ... 129.0 mg/l / 0.1 mg/l
Compensation Range: K+: 0.1 ... 1,000 mg/l / 0.1 mg/l
Measuring Accuracy in laboratory standard solutions
± 5 % of measured value ± 0.2 mg/l in standard solutions

∙ s::can plug & measure
∙ measuring principle: ISE (ionselective electrodes) - with potassium compensation
∙ multiparameter probe
∙ long term stable, factory precalibrated
∙ automatic cleaning with compressed air
∙ easy & quick mounting and measurement directly in the media (InSitu) or in a flow cell (monitoring station)
∙ ISE refurbishment - the easy way to minimise maintenance
∙ unique, non-porous / non-leaking reference electrode for technically unrivalled and consistent performance
∙ operation via s::can terminals & s::can software
∙ automatic temperature and potassium compensation, pH compensation possible
∙ ideal for surface water, ground water, drinking water and waste water
∙ minimal maintenance
∙ life time of ISE: typically 6 month (for applications <1mg/l NH4-N), resp. 1 to 2 years (for applications >1mg/l NH4-N)
∙ plug connection or fixed cable
