Hanna Checker Ammonia LR HI700
The Hanna Checker Ammonia LR HI700 is 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 Hanna Checker Ammonia LR HI700 provides quick, accurate results in a few easy steps.
Four simple steps to results
- First, add sample to the included cuvette.
- Next, insert sample into the Checker and zero the instrument with your water sample.
- Remove sample and add the reagent
- Finally, place the vial into back into the Hanna Checker, press the button and read the results
