Nitrate testing for water
NS2 is building a single-use nitrate strip for the same reader, scheduled for 2027 in freshwater and marine variants.
Nitrate is the compound that tells you how far nitrogen has travelled through a system — in a pond, a river or a treatment line. The nitrate cartridge is being developed for the reader you use today, so the same toolbox gains the measurement without new hardware.
What it measures
Nitrate, reported as nitrogen, in freshwater and marine samples, with the same one-drop format as the nitrite strip.

Frequently asked questions
When does the nitrate strip ship?
Nitrate is scheduled for 2027, in both freshwater and marine variants.
Will it work with the reader I buy today?
Yes. The reader reads every NS2 cartridge, so the same device covers nitrate when it arrives.
What sample does it need?
One drop, 50–70 µL, with no preparation.
Can we take part in a pilot?
Yes — tell us your water type and matrix through the contact form and we will get in touch.
How will results be recorded?
The same way as every NS2 test: over Bluetooth to the app, logged by sample and site.
