The HI733 Checker® HC (Handheld Colorimeter) provides a simple, accurate and cost-effective way to measure ammonia. Present in water as a component of the nitrogen cycle, ammonia is excreted from animals and other organisms such as heterotrophic bacteria, actinomycetes, and fungi during the metabolism of proteins and amino acids. Generally present in small quantities in unpolluted waters, higher levels indicate organic pollution and is toxic to aquatic life. Designed as a more accurate alternative to chemical test kits, the HI733 provides quick, accurate results in four easy steps:
*1 ml of sample is added to a cuvette with 9 ml of reagent “B”. The cuvette is then placed in the meter and the button pressed to zero.
- Easier to use and more accurate than chemical test kits
- Dedicated to a single parameter
- Small size, big convenience
- Ideal for: Water Quality, Aquaculture, Education, Industrial
Ammonia Range 0.0 to 99.9 ppm as NH₄⁺ Ammonia Resolution 0.1 ppm Ammonia Accuracy ±1.0 ppm ±5% of reading Ammonia Method adaptation of the ASTM Manual of Water and Environmental Technology D1426-92, Nessler Method. The reaction between ammonia and reagents causes a yellow tint in the sample.
