The HI 96720 measures the calcium hardness content, as CaCO3, in water and wastewater in the 0.00 to 2.70 mg/L (ppm) range.
This meter uses 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. The cuvettes are made from special optical glass to obtain best results.
