About Greentest Our company dedicates ourselves to changing the quality of life and protecting us and our children from the infringement of harmful impurities, nitrates and nitrites. As a result, a revolutionary new food safety testing device Greentest, has been developed, which allows detecting fruits and vegetables cultivated improperly and evaluating the concentration of nitrates. It helps us satisfy our "greenlife" desires to rub the lamp.Works by measuring the electrical conductivity of the fruit or vegetable matter being tested. Calibrated through extensive testing.How healthy are your fresh fruit and vegetables?Fertilizers that contain necessary elements for plant growth are used for cultivating fruits and vegetables. However, misuse of production technology, usage of prohibited fertilizers, pesticides and chemicals, as well as an increased level of fertilizer concentrations can all result in a serious damage to your health and risk of serious diseases. Nitrates cause serious diseaseIt has long been established that excessive nitrates are harmful to health. Greentest Nitrate TesterVegetables and fruits contains various amounts of salt ions, 98% of which are nitrate ions.The Greentest probe applies a precisely regulated electrical current to a fruit or vegetable specimen.The proprietary Greentest algorithm accurately calculates the specimen's nitrate content by comparing its electrical conductivity against a database obtained from exhaustive mass spectrometer testing of similar specimens under laboratory conditions.The results displayed are certified to be more than 90% accurate according to third party testing more than enough to determine the safety of the specimen.
