- Wastewater Treatment: Monitor ammonium in collection systems, influent, and effluent for compliance and process control.
- Drinking Water: Detect ammonia contamination in treatment plants and distribution networks.
- Environmental Monitoring: Assess surface water and groundwater quality for pollution and ecosystem management.
- Industrial Processes: Track industrial effluent to meet discharge limits and maintain water quality in manufacturing.

ammo::lyser pro
A multi-parameter probe for the online measurement of ammonium. It is an absolutely reliable device that outclasses conventional analyzers in terms of measurement stability and lifetime. Precision is guaranteed by real-time compensation of the ammonium value with temperature, pH, and potassium and a high-performance reference electrode.
ammo::lyser™ III pro: monitors NH4-N and temperature
ammo::lyser™ IV pro+pH monitors NH4-N, temperature, and pH (with potassium compensation)
ammo::lyser™ IV pro+NO3-N monitors NH4-N, temperature and NO3-N (with potassium compensation)
- s::can plug & measure
- Measuring principle: ISE (ion selective electrodes) – with optional potassium compensation
- Multiparameter probe
- Long-term stable, factory precalibrated
- Automatic cleaning with compressed air
- Unique, non-porous / non-leaking reference electrode for technically unrivaled and consistent performance
- ISE refurbishment – the easy way to minimize maintenance
- Easy & quick mounting and measurement directly in the media (InSitu) or in the flow cell (monitoring station)
- Operation via s::can terminals & s::can software
- Automatical temperature compensation, pH compensation are possible
- Ideal for surface water, groundwater, and drinking water, and also for applications in wastewater
- Minimal maintenance
- The lifetime of ISE: typically 6 months (for applications <1mg/l NH4-N), resp. 1 to 2 years (for applications >1mg/l NH4-N)
