HI96728 Nitrate 0.0-30.0 mg/L - Photometer mobile

Product information "HI96728 Nitrate 0.0-30.0 mg/L - Photometer mobile"

Nitrates are present in nature as a result of 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 (ppm) 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 (ppm), 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 HI 96728 meter measures the nitrate content in water and wastewater.

This meter uses an exclusive positive-locking system to ensure that the cuvette is in the same place every time it is placed into the measurement cell.
