This test strip is for the rapid and reliable determination of Nitrate and Nitrite in solutions. The easy dip-and-read-procedure provides a reliable result within 1 minute.
Nitrite is an undesired byproduct in cooling lubricants. It allows the formation of carcinogenic compounds. Cooling lubricants are therefore regularly tested for Nitrite.
In natural and drinking water Nitrite can lead to infant mortality and dead aquatic life. The EPA primary drinking water standard is 1 mg/l.
