Ammonia is a common byproduct from the breakdown of proteins and is excreted by animals as ammonia, urea or uric acid. Ammonia is also a commonly found in fertilizer and used as a nitrogen source for plant growth. It is effective in cleaning chemical and can be found in glass and floor cleaners. Ammonia exists in two forms. One is the ionized form ammonium (NH4+) and the other is the gaseous form ammonia (NH3). The relationship in which form is present is based on the pH of the solution with ammonium becoming more predominate at pH’s less than 8. Since most naturally occurring water is pH 8 or less, ammonium is the most common form present. For aquatic life, as the pH increases this can be lethal as the ammonium is converted to ammonia, which is more toxic since it can diffuse back into the animal. In surface and groundwater, unless there is some contamination, the concentration is very low. In drinking water it is common to add ammonia to water at concentrations less than 0.4 mg/L to extend the effectiveness of chlorine as a disinfecting agent. Using the Nessler method the HI 97700 is designed to measure ammonia in the low range at levels from 0 to 3.00 mg/L ammonia – nitrogen. The results can be displayed as ammonia or ammonium as well.
The HI97700 has an innovative optical system that offers superior performance in accuracy, repeatability, and the short amount of time it takes to perform a measurement. This compact, waterproof meter is extremely user friendly with a tutorial mode that walks the user graphically, step by step, in performing a measurement. The use of a backlit dot matrix LED allows the use of virtual keys which makes the operation of the meter very intuitive including selecting different units of measure, reviewing GLP data, recalling the last 50 measurements, and customizing the meter to user preferences.
HI97700 is completely waterproof including the cuvette holder that is designed with ridges to protect the optical path from getting scratched by the cuvette and a gasketed battery compartment that holds three common AA batteries. The compact design fits comfortable in the hand for use in the field or on a table for benchtop use. The LCD is 71 mm (2.75″) by 37 mm (1.6″) and is backlit for easy viewing under all conditions
