Measures the total hardness in drinking, surface and wastewater. Many advanced features are offered with this device, including the exclusive CAL Checkª function used for performance verification and calibration of the meter. Total hardness is due mainly to the runoff water dissolving these salts as it flows or filters through different strata.

This is the direct replacement:
Using an exclusive positive-locking system to ensure that the cuvette is in the same position every time it is placed into the measurement cell. It is designed to fit cuvettes with a larger neck making it easier to add both sample and reagents. Using ready made reagents a user can accurately determine the total hardness concentration in samples. Low range measures from 0 to 250 mg/L CaCO3, medium range measures from 200 to 500 mg/L CaCO3, and the high range measures from 400 to 750 mg/L CaCO3.
