The HI97749-11 Chromium VI CAL Check™ Standards provide a simple solution to calibrating and validating the compatible HI97749 portable photometer. This high quality set of standards is manufactured in our state-of-the-art facility and comes supplied with a certificate of analysis. The certificate of analysis provides the lot number, reference values, and expiration date for traceability when certifying the compatible chromium VI photometer.
HI97749-11 is a high quality set of calibration standards that allows users to validate and calibrate the chromium VI range found in the compatible HI97749 photometer that has a 0 to 300 µg/L (ppb) chromium VI range. The HI97749-11 includes one sealed “A” cuvette for zeroing the meter and one “B” cuvette that is used to validate or calibrate. The expected reading from the “B” standard is 100 ±5 µg/L chromium VI @ 25℃. The calibration set is produced in our state-of-the-art manufacturing facility using reagent grade chemicals in a temperature controlled environment.
