 Nitrates are present in nature as a result of the decomposition of organic microorganisms or due to their use as fertilizers. Nitrates reduce to nitrites, which in turn easily combine to form substances dangerous to man.
A maximum level of 45 mg/L is established as a worldwide guideline for nitrate concentration in water. In Europe, the maximum consented level of nitrates in potable water is 50.0 mg/L, while in the USA the EPA has established a guideline for the maximum level of nitrate nitrogen of 10 mg/L (NO-3-N), which corresponds to 45.0 mg/L of nitrates.
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.
For the full product specification and accessories required please see the attached instruction manual.
The HI-93728 is supplied complete with cuvets, battery and instructions.
Reagents NOT included.
