HI3873 ชุดตรวจหาไนไตรท์ Nitrite Test Kit ย่านการวัด 0.0 ถึง 1.0 mg/L ความละเอียด 0.2 mg/L (Method Chromotropic acid)

The HI3873 is a colorimetric chemical test kit that determines the nitrite concentration in samples within a 0.0 to 1.0 mg/L (ppm) range as nitrite-nitrogen (NO2–N). The HI3873 is supplied with all of the necessary reagents and equipment to perform the analysis. The test kit contains enough reagents for perform approximately 100 tests.

Features

Complete setup

• All required materials are included with the test kit, such as the glass cuvette, color comparison cube, and reagent packets.

High resolution

• Readings from 0.0 to 1.0 mg/L are determined to 0.2 mg/L resolution.

Replacement reagents available

• There is no need to buy a new kit when reagents are exhausted. The HI3873-100 can be ordered to replace the reagents supplied with the kit.

Significance of Use

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