Nitrate Analyzer Tester, Packaging Type : Black

EcoLifePro 2 nitrate meter is a hand-held device, designed to measure the quantitative nitrate content (rapid analysis) in fresh fruits, vegetables, meat and infant food. The device also can be used as salinometer (TDS-meter) that measures the concentration of water-insoluble inorganic impurities (the salts of different metals generally). 
The nitrates are the nitric acid salts (NO3), contained in the soil and absorbed by the plants from the soil. Thanks to their positive influence on the crops growth and fertility, and the harvest ripening speed, nitrates are widely spread in agriculture. When getting into human body, nitrites react with its microflora and transform into nitrites (NO2). The nitrites are absorbed into the blood stream from the intestinal tract and having aggregated with hematoglobulin form methylhemoglobin. Methylhemoglobin is a stable chemical compound that doesn̢۪t transport oxygen. It induces hypoxia, accumulation of lactic acid in tissues, tissue intoxication and histolysis.
However most researchers today believe that the cancer is the main danger, especially the gastro-intestinal cancer. With the nitrites, cancerogenic nitrate amides and amines can be synthesized from almost any food both in stomach and intestinal tract.
