Review on Greentest ECO6 by Mateusz Grabowski ᠌

A useful device for anyone who thinks about their health. Quickly measures nitrate levels in vegetables, fruits, fish and meat, all in just a few seconds. I used to use another nitrate meter, and there was just a huge probe that left holes on the products. The same probe is double and thin, there are practically no traces. Water hardness and radiation can also be measured. I have not used the last function yet, but I began to check drinking water regularly.
