Hexavalent Chromium Photometer with 555 nm LED
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.
HI 93749 is supplied with 2 cuvets, battery and instructions.
