- High resolution
- Readings from 0.0 to 1.0 mg/L Cr+6 are determined with a smallest increment of 0.2 mg/L.
- Replacement reagents available
- There is no need to buy a new kit when reagents are exhausted. The HI3846-100 reagent set can be ordered to replace the reagents supplied with the kit. This reagent set comes with 100 packets of HI3846-0 reagent.
Significance of Use
Chromium salts are widely used in industrial processes such as metal finishing and plating, as well as in the leather industry as a tanning agent, and in the manufacture of paints, dyes, explosives, and ceramics. Chromium may enter a water supply through the discharge of waste from these industries or from chromate-treated cooling waters, where it is frequently added for corrosion control. The hexavalent state of chromium, CrVI, is toxic to humans, animals, and aquatic life; it can produce lung tumors when inhaled and readily induces skin sensitization.
