How Greentest nitrate testers work and how to read the result
Greentest household devices work as conductivity meters: they analyze the overall salt content in a product and, taking into account pulp juiciness and density, approximate the relative nitrate level at the puncture point. Since nitrates are distributed unevenly, it is better to test two or three different spots. The device is calibrated for fresh products without heat treatment. You do not need to look up limits manually: the necessary data is already built into the menu. The result appears in 3-5 seconds. Depending on the model, Greentest can also measure background radiation and water hardness.
- Select a product on the touch screen, insert the probe into the pulp and press “Test”
- First result in 5 seconds
- The device shows a digital result and a color assessment: green, orange or red
- For a more accurate result, make 2-3 punctures in different places
