What technology we are using to detect nitrate?
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 equipmentGreentest, 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.
Switch on the power on top of the Greentest, select from the screen (menu) the fruits or vegetables you need, and then take the chosen
fruitsor vegetables, pull off the lid on the bottom of the Greentest, wipe it dry and clean with dry cloth or tissue, then you can get the
most accurate result. Use the probe to penetrate the skin of the fruits or vegetables, press "start testing", a few seconds later, Greentest
screen the will show thenitrate content of the tested fruits or vegetables. For people to understand more vividly, Greentest screen is designed
to use three colors to distinguish nitrate content: Green means the amount is normal and safe; yellow means excessive; when the screen is
red, it means that the nitrate content inthe fruits and vegetables has been seriously overweight to the point of danger.
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
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.
This food safety equipment 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.
