Calcium presence in water supplies results from passage over deposits of limestone, dolomite, gypsum and gypsiferous shale. The concentration may extend from 0 to several hundred milligrams per litre, 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 HI758 Calcium Checker®HC is extremely simple to use. First, zero with Reagent A and deionised water. Next, remove the vial and add sample and 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.
Weighing a mere 64 g (2.25 oz.), the Checker®HC easily fits into your hand or pocket.
