PDF Catalog
As one of the most common forms of disinfection, chlorine improves water quality by destroying disease-producing microorganisms, and by reacting with other organic and inorganic substances.
There are instances when water needs to be de-chlorinated and then checked to determine if the chlorine concentration is beneath a threshold level. The HI97762 is a portable photometer designed to monitor very low levels of chlorine. The HI97762 uses an adaptation of method 4500-CL G, DPD colorimetric method from the Standard Methods for the Examination of Water and Wastewater.
When the HI95762-0 DPD reagent is added to a sample containing free chlorine, the sample will turn a pink hue; the greater the concentration, the deeper the color. HI97762 measures free chlorine from 0.000 to 0.500 mg/L (ppm).
The HI97762 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.
