Ammonium Ion Selective Electrode ISE
Use ammonium ion selective electrode (ISE) to measure the NH4+ ion in aqueous solutions.
Ammonium electrode is a half-cell probe, and is able to detect ammonium ions. This type of ISE is all-solid state, based on the carbon nanotube technology. As result, this sensor is built-up with robust body, solid-state and membrane selectivearea. Ammonium ion selective electrode is compatible for use with any Ion or mV meter and a reference electrode.
Above all, the ammonium sensor is ideal for measuring NH4+ concentrations in drinking water, tap water, wastewater and general water quality applications; for example:
- Unique solid-state sensor nanotechnology inside.
- Requires virtually zero maintenance.
- Provides fast, stable, and accurate response in a variety of sample types.
- Replaceable sensor tip.

Where is ammonium measurement required so far?
Ammonium ion is mainly encountered as a waste product in municipal wastewater in the form of urea. As a consequence, water sources with an ammonium concentration of 1 mg/l are not suitable. The use the ammonium ion selective electrode helps to know your water quality and avoid serious problems.
Some specific use of the ammonium electrode are; for example:
- Studying the spread of harmful substances from diffuse sources.
- Monitoring aquaculture crops to point out dirtiness due to excessive nutrient concentration.
- Monitoring nutrient content in natural waters.
- Measure ammonia introduced from fertilizers.
- Can monitore the equilibrium and indicate aqueous ammonia levels when samples are acidified to convert NH3 to NH4+.
