Markets
Water testing for aquatic ecosystems
Nitrite, nitrate and ammonium in rivers, lakes and coastal water, measured in the field rather than in a lab.
Give field teams lab-grade nitrogen readings at the sampling point.

Frequently asked questions
Can one device cover rivers, lakes and coastal sites?
Yes. The same reader reads nitrite strips for both freshwater and marine sites, so one toolbox works across a catchment.
Will cloudy or coloured water affect the result?
No. NS2 measures an electric current rather than a colour, so turbidity does not distort the reading.
How fast is a field result?
About three and a half minutes from one drop, with no calibration step before the test.
What is the measurable nitrite range?
0.025–5 mg/L as nitrogen, which covers most monitoring work in fresh and coastal water.
Can we export data for a monitoring programme?
Results are logged by sample and site in the app and can be exported for reporting.
