Chromium
VI High Range Checker HC®, 0 to 999 ppb
The
Hanna Chromium VI High-Range Checker® bridges
the gap between simple chemical test kits and professional
instrumentation. Chemical test kits have limited accuracy and resolution
since they rely upon the human eye to discern differences in color.
Professional instrumentation incorporates a light source such as an LED or
tungsten lamp with a filter and a light sensing detector to precisely
determine absorbance and ion concentration. Professional instrumentation
offers greater resolution and accuracy but can cost hundreds of dollars.
The Hanna Chromium VI High-Range Checker® uses
a fixed wavelength LED and silicon photo detector to provide the accuracy
of professional instrumentation at the affordable price of a chemical test
kit.

Operation
The
HI-723 Checker® HC
(Handheld Colorimeter) provides a simple, accurate and cost-effective way
to measure chromium VI. Due to its corrosion-resistant properties,
hexavalent chromium plays an important part in the plating industry and
cooling towers. However, due to its toxic and carcinogenic nature,
chromium VI must be must be sufficiently treated prior to wastewater
discharge. Designed as a more accurate alternative to chemical test kits,
the HI-723 provides quick, accurate results in four easy steps:
Features
-
Easier to use and more accurate than chemical test kits
-
Dedicated to a single parameter
-
Small size, big convenience
-
Ideal for water quality, plating, industrial
