Chromium
Low Range Checker (0-300 ppb)
The
Hanna Chromium VI Low-Range Checker (HI-749) tests for the presence of
Chromium VI (Hexavalent Chromium) in concentrations within the range
of 0 to 300 ppb with an accuracy of ±3 ppb in samples such as drinking
water and wastewater. With a digital readout, Hanna Checkers provide
greater measurement accuracy when compared with chemical test kits that
rely on human perception of color.

Operation
The
HI-749 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-749 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, education, industrial, municipal water
