Easily monitor nitrite levels in closed-loop cooling systems with this liquid reagent. Proper control of nitrite levels prevents pipework corrosion. This easy-to-use colourimetric method test can monitor high levels (up to 2,500 mg/L) of nitrite without the need to dilute samples.

Unlike similar colourimetric tests on the market, this test provides the full testing range industrial water treaters need and avoids the release of potentially harmful nitrogen oxides during testing.
