Hanna Instruments HI723 is a portable colorimeter for the determination of Chromium VI in water. It features a high range of 0 to 999 ppb with a resolution of 1 ppb and an accuracy of ±5 ppm ±4% of reading. The HI723 uses the Adaptation of the ASTM Manual of Water and Environmental Technology, D1687-92, Diphenylcarbohydrazide method. The reaction between chromium VI and the reagent causes a purple tint in the sample, which is then measured by the colorimeter. The HI723 is easy to use, with a simple two-button operation.
