Nitrite testing for water
A single-use electrochemical strip that gives you a nitrite number in minutes, from one drop, in freshwater or marine water.
Nitrite builds up fast in a tank, a pond or a treatment line, and the number that matters is the one you can get where the water is. The NS2 nitrite strip is sealed in a foil pouch and pre-calibrated for the reader: open the pouch, add one drop, insert, and the result appears on your phone in about three and a half minutes.
What it measures
Nitrite, reported as nitrogen, across a range of 0.025–5 mg/L. The enzyme layer in the strip reacts with nitrite, so other ions in the sample do not move the reading.

Frequently asked questions
What is the measurable range?
0.025–5 mg/L as nitrogen.
How long does the test take?
About three and a half minutes from one drop of water.
Is it available for marine water?
Yes. Nitrite strips are available today in freshwater and marine variants.
How long does a strip stay usable?
Six months unopened and one hour once the pouch is opened, stored dry at 2–8 °C.
Do I have to calibrate it?
No. Each strip is pre-calibrated and carries its calibration in a QR code the reader reads.
