Its concentration may\nextend from 0 to several hundred milligrams per liter, depending on its source\nand treatment. Calcium is necessary in plant and animal nutrition since it is\nan essential constituent of bones, shells and plant structures. Calcium in\nwater as carbonate is one of the primary components of water hardness which\ncan cause pipe or tube scaling. The HI 758 Calcium Checker HC is extremely\nsimple to use. First, zero the instrument by adding Reagent A, deionized water\nand 0.1 mL of sample into the vial. Insert into the HI 758 and press the\nbutton. Next, remove the vial and add Reagent B and shake to dissolve.\nReinsert into the Checker HC and press the button to read the calcium\nconcentration in ppm on the display. Use for quick and accurate on the spot\nanalysis. Single button operation: zero and measure. Range: 200 to 600 ppm.\nResolution: 1 ppm. Accuracy at 25 degree C: +\/-6% of reading. Light Source:\nlight emitting diode at 610 nm. Light Detector: Silicon Photocell.\nEnvironment: 0 to 50 degree C (32 to 122 degree F); max 95% RH non-condensing.\nBattery Type: (1) 1.5V AAA. Auto-off: after 10 minutes of non-use. Dimensions:\n81.5mm x 61mm x 37.5mm (3.2\" x 2.4\" x 1.5\").
