No more struggling to determine colours with Test Kits, our handheld photometers take the hassle out of matching to a colour chart, providing a direct and precise result.
Nitrite is added to water in cooling towers at high concentrations to act as a corrosion inhibitor.
Food Industry uses Nitrite compounds as preservatives.
It is present in low concentrations in surface waters and rarely in groundwaters.
In wastewaters, nitrite concentrations are often higher.
Nitrite is produced during the bacterial oxidation of ammonia and in the reduction of nitrate.
Applications
Rapid checks for dairy, beverages, sauces, and process-line compliance.
Field testing for municipal and industrial water treatment monitoring.
Keep display and breeding tanks stable — pH, ammonia, nitrite and dissolved oxygen.
