Clarkson HI93723
Hexavalent Chromium Photometer High Range with 555 nm LED
Hanna Instruments HI 93723
Description:
At normal temperatures chromium is corrosion-resistant. For this reason, it plays an important role in
the plating industry as well as cooling towers. In addition, it has certain qualities that make it useful in
the production processes of the textile industry.
Hexavalent chromium is the most common form in which the metal is used, however, being highly
toxic it needs to be continuously monitored in industrial wastes.
HI 93723 and HI 93749 are the ideal meters to perform accurate and quick measurements of
chromium concentrations within the ranges of 0 to 1000 µg/L and 0 to 300 µg/L, respectively.
They are supplied with cuvets and caps. Choose from packages of 100 or 300 reagents listed below
for your everyday use.
