Nitrites occur in water as an intermediate product in the biological breakdown of organic nitrogen, being produced either through the oxidation of ammonia or the reduction of nitrate. The presence of large quantities of nitrites is indicative of waste water pollution. Low range nitrite estimation is useful for drinking water analysis. Nitrite is added to control corrosion in closed cooling systems. We have two kits for nitrite one a very low range, especially for drinking and the higher one for waste water. Our AQUASOL kits are based on colour comparison. They are very simple and convenient to use.
