HANNA – HI96735

Total Hardness EPA Portable Photometer

The HI96735 Total Hardness EPA Portable Photometer combines accuracy and ease of use in an ergonomic, portable design. Using the HI93735-0 ready made reagents a user can accurately determine the total hardness concentration in samples within a low, medium, and high range. The low range measures from 0 to 250 mg/L CaCO3, the medium range measures from 200 to 500 mg/L CaCO3, and the high range measures from 400 to 750 mg/L CaCO3. Users can simply choose the appropriate range depending on their expected sample concentration. The HI96735 offers many advanced features including the exclusive CAL Check function used for performance verification and calibration of the meter.
