Product Details

The Hanna Chromium VI Low-Range Checker (HI749) tests for the presence of Chromium VI (Hexavalent Chromium) in concentrations within the range of 0 to 300 ppb with an accuracy of 3 ppb in samples such as drinking water and wastewater. With a digital readout, Hanna Checkers provide greater measurement accuracy when compared with chemical test kits that rely on human perception of color.
