Details
- The HN/000733 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 HN/000733 provides quick, accurate results in a few easy steps

Features at-a-glance
- 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
