This document is an instruction manual that provides information on the use and specifications of the HI 95721C Iron High Range ISM iron high concentration meter.
The HI 95721C is an auto diagnostic portable microprocessor meter designed to measure total iron (Fe) content in water samples within the 0.00 to 5.00 mg/L range. It features an advanced optical system based on a special tungsten lamp and a narrow band interference filter, along with a powerful CAL CHECK validation function to ensure performance. The instrument is splash waterproof and includes an auto-shut off feature.
