HI97700 is an advanced portable photometer for the low range measurement of ammonia in water.  This meter offers a superior optical system that utilizes a reference detector and narrow band interference filters for extremely fast and repeatable measurements

• CAL Check to verify meter performance
• Tutorial mode for step-by-step instructions
• Display results in multiple chemical forms

This portable photometer 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.
