Greentest not justa food detector, it is Professional Home Food Detector. We hope that every family can keep away from unhealthy , contaminated food and stay healthy. Wonderful Technology protecting us and our children from the infringement of harmful impurities, nitrates and nitrites. It helps us satisfy our “greenlife” desires to rub the lamp.   GREENTEST-A Scientific Approach To FOOD SAFETY Lower resistance = higher nitrate content The presence of nitrate ions in organic matter measurably increases conductivity. This measurement differs according to the ion concentration and cell structure of the fruit or vegetable under test. Calibrated through extensive testing Our scientists developed the Greentest nitrate content protocols by using a mass spectrometer to determine nitrate levels in a large number of fruit and vegetable specimens. Testing a range of specimens under laboratory conditions allowed us to establish normative levels for various fruit and vegetable species. A high degree of accuracy The results were applied to test algorithms which have been coded into the Greentest device. The device has been extensively back-checked against specimens that were subsequently tested with a mass spectrometer. The device is certified to be more than 90% accurate according to third party testing. This is more than sufficient to produce a valid assessment of nitrate content. GREENTEST-Food Radiation Detection Determines radiation in 10 seconds  Just 10sec,gives us the answer to the actual question: "Does this product is harmful for my health or not?". Radiation containing products, not only means that we can not eat it, and should stay away from it. Radiation detection don't need to use the probe, just close the device to the item and click the "radiation", after 10 seconds will show the radiation value.  And show the current environmental radiation value of: Normal (Green); Elevated (Yellow); Dangerous (Red).   Who Buys It   People who want to take better care of themselves and their loved ones, and especially their kids. People who want to make informed healthy choices about the food they eat. People who want to eat healthier with less meat and more good quality fresh fruit and vegetables People who understand the problems associated with modern agricultural practises. People who want to demonstrate the safety of the food they serve. People who want to give someone a useful gift. There Is A Difference Now you can identify unhealthy fruit and vegetables with this portable fruit and vegetable nitrate tester Protect yourself and protect your family Simply insert the probe into your sample Easy-to-read test results in just 3 seconds Greentest works by measuring the electrical conductivity of the fruit or vegetable matter being tested.
