The HI3826 is a chemical test kit that uses the Nessler method to measure ammonia in seawater. The HI3826 is supplied complete with all of the reagents and equipment necessary to perform approximately 25 tests.
Pre-made reagents for ease of use
All reagents marked with expiration date and lot number for traceability
All required materials are included with the test kit, such as the sample beaker, color comparison cube, and reagent dropper bottles.
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 HI3826-025 reagent set can be ordered to replace the reagents supplied with the kit. This reagent set comes with 1 (20mL) dropper bottle of Ammonia Reagent 1 for Seawater and 1 (20mL) dropper bottle of Nessler Reagent.
Significance of Use
Concentrations of ammonia in rivers, estuaries, and bays may indicate the presence of agricultural runoff or urban pollution. When the concentration of ammonia is high enough, it can prove toxic to aquatic life, affecting the survival, growth, and reproduction rates of various marine species. In industrial applications, high concentrations of ammonia can cause corrosion in pipes.
