ITT Corporation‘s WTW and OI analytical instrument brands offer a range of measurement options for the detection of the carcinogenic hexavalent chromium (chromium VI) in drinking water supplies. The WTW pHotoFlex Photometer offers a simple, portable lab, while the pHotoLab 6100 VIS research grade spectrophotometer offers flexibility while minimizing bench space. Chemistry test kits are available in a variety of sensitivity levels, and meet the current US EPA detection limits. The OI Analytical DA 3500 colormetric discrete analyzer measures multiple analytes (e.g., chromium VI, phosphate and nitrite) concurrently, allowing samples to be analyzed immediately upon receipt in the laboratory, within the US EPA 24-hour requirement.www.ittanalytics.com
