Greentest ECO 6 Instant Read Digital Nitrate Tester, Water Meter TDS PPM Radiantion Detector Geiger Counter Combo for Fresh Meat,Fruit,Vegetable

Definitely not as accurate like a 100k machine in the lab but if a food product has high nitrit level will show it as high no matter how many times you measure, so yes it does the job

I bought this device a month ago and was thinking that was everything fine. I did have however some concerns about water hardness tests but could not prove that was anything wrong. Yesterday I did check potatoes from two sources to compare. The reading of the worst potato was 300mg of Nitrates so it was above the safe tolerance. When I checked the same potato again, second time the same piece was tested 220. I had picked up another potato which result was 150 at the first time. Second measurement shown the figure of 120 and the third test result was 100 of the same potato. Very inaccurate and would not recommend it. The reason why I bought it was the price in comparison to the competitors but even that money seems to be wasted.

Best device to have for your home

This device is inaccurate. I have have read manufacture instruction and followed all steps each time prior to use but measurements were not correct and some times false. I would not recommend this device to any one to buy it. Waste of money.
