Nitrite detector

The Rapid Nitrite Detector for Food is an integrated food safety testing and analysis device capable of quickly detecting nitrite levels in meat, canned meat, smoked meat, sausages, dairy products, pickles, pickled vegetables, and other food items; The instrument is based on GB5009.33-2010 “Determination of Nitrites and Nitrates in Food.” Nitrites in food are extracted, react with detection reagents to form colored compounds, and then measured using the nitrite detector to determine their absorbance. Within a certain range, absorbance is directly proportional to concentration. Through testing, it can be determined whether food meets national standards or is contaminated with excessive levels of nitrites.

The instrument reserves additional testing programs and ports, allowing users to conveniently add new testing projects as needed in the future. It can be upgraded to a comprehensive instrument capable of testing aquatic products and flour-based foods.

The nitrite detector can rapidly test nitrite levels in meat, canned meat, smoked meat, sausages, dairy products, pickles, pickled vegetables, and other foods. It is widely used in food safety testing, food and drug administration bureaus, health departments, meat product processing enterprises, supermarkets, quality supervision and inspection agencies, industrial and commercial administration departments, fried food production bases, and various food safety monitoring systems.
