Hanna HI720 Calcium Hardness Checker® HC – 0.00 to 2.70 ppmThe Hanna HI720 Checker HC is an elite, pocket sized digital colorimeter designed exclusively for the measurement of Low Range Calcium Hardness in water. Utilizing the Calmagite method, it provides precision readings from 0. 00 to 2. 70 ppm (mg L) as CaCO3. It replaces subjective visual color matching tests, serving as the primary QA instrument for monitoring industrial boilers, RO plant efficiency, and high end water softening systems. Prevent

A: The HI735 uses a combination of liquid and powder reagents (HI735-25) to ensure the highest possible accuracy for Total Hardness

The tool also features an electronic brake that stops the motor immediately upon deactivation

Lower Noise Profile: The belt-drive mechanics operate noticeably smoother and quieter (83dB) than high-RPM direct-drive units

this photometric test works perfectly on completely still water samples
