HI 93708

Nitrite Photometer with 585 nm LED

          Nitrites are an intermediate product in the nitrogen cycle and are produced ammonia oxidation with water, or even originate in industrial waste directly. They must not be present in drinking water.

Nitrites can be harmful to aquatic organisms even in low concentrations and for this reason, they are closely monitored in aquaculture facilities. In cooling towers, however, an adequate amount of nitrites is necessary to prevent corrosion.

In high concentrations, they can be harmful to the environment and to humans. They are, therefore, normally monitored to verify the quality of water for domestic use, as well as lakes and ponds.

HI 93707 and HI 93708 show the nitrite concentration directly in the 0.00 to 0.35 mg/L and 0 to 150 mg/L ranges, with increments of 0.01 mg/L and 1 mg/L, respectively.

They can also determine sodium nitrite concentrations by simply multiplying the readings by 4.93 (HI 93707) or by 1.5 (HI 93708). With HI 93708 it is also possible to determine nitrogen nitrite concentrations by dividing the readings by 3.29.

Order Information:
HI 93708 is supplied with 2 cuvets, battery and instructions.
