Hanna Instruments Water Analysis Division has released the HI 95707, providing an affordable analysis of nitrite content, with a high resolution from 0.000 to 0.600 mg/L. The analysis requires only the use of a single sachet containing the correct dose of reagent. Validating the instrument is possible at any time with the Cal Check standard cuvets.

Nitrites are not found in superficial waters, because they oxidate rapidly and become nitrates. The presence of high levels of nitrites indicates organic waste decomposition in the tested water. Nitrites are the intermediate stadium of biological decomposition of compounds containing organic nitrogen, for example in waste water, in natural water and in distribution water systems. However, in cooling towers an adequate amount of nitrites is necessary to prevent corrosion.

The HI 95707 is supplied with two cuvets, a battery and instructions. The HI 95707C kit includes the HI 95707, a rugged carrying case, scissors, tissue for wiping cuvets and the Cal Check standard.
