> 3 dayI performed accurate calibration using distilled water and nitrite-ion calibration solution. Every time testing results were 2-4 times lower than expected. 0 and 0,1 values are not distinguishable at all. It is hard to match sulution and scale colors because scale has much more of red.

> 3 dayThe description on the Amazon site claims this product measures nitrate. IT DOES NOT!!! This is a misprint by an idiot. Nitrite is deadly; nitrate is added to bacon.
