Reliable Results at Home

Simple, accurate nitrate testing for your well, garden, lawn, aquarium, or community project. Our home kits are simplified versions of NECi’s validated laboratory methods, with pre-measured reagents and the calculations done for you. Non-toxic and trusted since 1993.

No instrument needed. Results are read by eye against the color chart. The water kit comes in two ranges: Standard Range (0.5–10 ppm nitrate-N) for wells, drinking water, and freshwater aquariums and aquaculture, and Low Range (0.1–2.0 ppm nitrate-N) for ambient, unimpaired streams, lakes, and groundwater. 

Private wells aren’t covered by federal testing requirements, so regular testing is up to the owner. These kits are for screening and monitoring. Use a certified lab for compliance or real estate testing.
