This manual introduces the basic information of HI 96719C Magnesium Hardness ISM, including function, usage, maintenance, etc.
The HI 96719 is an auto-diagnostic portable microprocessor meter designed to measure magnesium hardness content as CaCO3 in water and wastewater within a range of 0.00 to 2.00 mg/L (ppm). It utilizes the EDTA colorimetric method adapted from Standard Methods for the Examination of Water and Wastewater, 18th edition. The instrument features an advanced optical system with a tungsten lamp and narrow band interference filter to ensure accurate and repeatable readings.
