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 methods, reviewing GLP data, recalling the last 50 measurements, and customising the meter to user preferences.\u003c\/p\u003e \u003cp\u003eHI-97707 is waterproof including the cuvette holder that is designed with ridges to protect the optical path from getting scratched by the cuvette and a protected battery compartment that holds three 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.\u003c\/p\u003e \u003ch3\u003eAdvanced LED optical system\u003c\/h3\u003e \u003cp\u003eLEDs have a much higher luminous efficiency, providing more light while using less power.

In cooling towers, however, an adequate amount of nitrites is necessary to prevent corrosion. In high concentrations, they can be harmful to the environment and to humans. They are, therefore, normally monitored to verify the quality of water for domestic use, as well as lakes and ponds.\u003c\/p\u003e \u003cp\u003eNitrites are an intermediate product in the nitrogen cycle and are produced by ammonia oxidation with water, or even originate in industrial waste directly.
