This is a combination purchase of one HI 758 Checker + one HI 758-26 reagent pack (good for 25 tests). Calcium presence in water supplies results from passage over deposits of limestone, dolomite, gypsum and gypsiferous shale. Its concentration may extend from 0 to several hundred milligrams per liter, depending on its source and treatment. Calcium is necessary in plant and animal nutrition since it is an essential constituent of bones, shells and plant structures. Calcium in water as carbonate is one of the primary components of water hardness which can cause pipe or tube scaling. The HI 758 Calcium Checker®HC is extremely simple to use. First, zero the instrument by adding Reagent A and deionized water. Insert into the HI 758 and press the button. Next, remove the vial and add Reagent B and shake to dissolve. Reinsert into the Checker®HC and press the button to read the calcium concentration in ppm on the display.
