The HI3824 is a colorimetric chemical test kit that determines the ammonia concentration in fresh water within a 0.0 to 2.5 mg/L (ppm) range as NH₃-N. The HI3824 is supplied with all of the necessary reagents and equipment to perform the analysis. The test kit contains enough reagents for perform approximately 25 tests.

Features at-a-glance

Complete setup 

• All required materials are included with the test kit, such as the sample beaker, color comparison cube, and reagent dropper bottles.

High resolution

• Readings from 0.0 to 2.5 mg/L NH₃-N are determined to 0.5 mg/L resolution.

Replacement reagents available

• There is no need to buy a new kit when reagents are exhausted. The HI3824-025 can be ordered to replace the reagents supplied with the kit.

Significance of Use

Groundwater normally contains ammonia due to bacterial decay of plants and animals. However, concentrations of ammonia in rivers and drinking water reservoirs may indicate the presence of agricultural runoff or urban pollution. When the concentration of ammonia is high enough, it can alter the smell and taste of water. In industrial applications, high concentrations of ammonia can cause corrosion in pipes. Ammonia is also monitored in fresh water aquariums and fish farming applications because of its toxicity to fish.
