1462/97_HI96752-11

The HI93752-03 are high quality reagents that are pre-measured, allowing for users to achieve fast and accurate colorimetric measurements. These reagents follow an adaptation of the calmagite method for determining calcium, and the oxalate method for magnesium. By simply adding the HI93752-03 reagents to the sample, the reaction will take place and one of Hanna’s compatible benchtop or portable meters will determine the concentration from the color that is produced. The results will be displayed in mg/L (ppm) as calcium or magnesium, depending on the method used. These reagents are designed to be used with samples that have an expected range of 0 to 400 mg/L calcium hardness, and 0 to 150 mg/L magnesium hardness
