Hanna Instruments HI96752 Calcium and Magnesium Portable Photometer with Sample Cuvettes, 7-19/32" Length x 4-3/32" Width x 2-11/16" Height, 1mg/L (ppm) Resolution, 9V Battery

The HI96752 measures two important parameters in agricultural and hydroponic applications. HI96752 measures calcium concentrations from 0 to 400 milligrams per liter and magnesium from 0 to 150 milligrams per liter and the values are displayed directly on the large LCD to eliminate the need for conversion tables. This handy and portable meter with a low cost-per-test is an ideal hi-tech alternative to chemical test kits. Accurate and cost-saving, this two in one portable photometer is factory calibrated to measure only calcium and magnesium, to provide an instrument that is easy to use in the lab or on the field. HI96752 is supplied with 2 sample cuvettes with caps, 9V battery and instruction manual. 1 milligrams per liter (ppm) calcium and magnesium resolution. +/-10 milligrams per liter +/-5 percent of reading for calcium and +/-3 milligrams per liter +/-3 percent of reading for magnesium at 25 degree C accuracy.
