Nitrates reduce to Nitrites which in turn easily combine to form substances dangerous to man. A maximum level of 45mg/L is established as a worldwide guideline for nitrate concentration in water.
The Hanna HI-93728 Nitrate Low Range Meter is extremely easy to use and gives direct readout on the digital display in mg/L(ppm). To obtain a reading simply take a small sample of water in the glass cuvette supplied, add the reagent (not included), and then place the cuvette in the measuring chamber of the instrument.
