Hanna Instruments Checker Marine Calcium Colorimeter Information


Product Manuals & Documentation



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.

Weighing a mere 64 g (2.25 oz.), the Checker HC easily fits into the palm of your hand or pocket!.
  • Ideal for Aquaculture and Aquarium testing!
  • Easier to use and more accurate than chemical test kits!.
  • Large, easy to read digits.
  • Auto shut off.
  • Operated by a single AAA battery
  • Use for quick and accurate on the spot analysis.
  • Single button operation: zero and measure.
Specifications:
  • Range: 200 to 600 ppm
  • Resolution: 1 ppm
  • Accuracy: +/- 6% of Reading
  • Battery Type: 1 - 1.5V AAA
Includes
  • Calcium Checker
  • 2 - Sample Cuvettes and Caps
  • Reagent Start Kit for 25 Tests

How it works:

The Hanna Marine Calcium Checker® HC HI758 is designed to make testing quick and easy.


  • Press the button to power the meter on. Notice “Add C1” appears on the screen. You are now ready to begin testing.
  • Using the 1mL syringe, add 1mL of reagent A to the cuvette. Then, using the dropper, fill the cuvette to the 10mL mark with deionized water. Distilled water is also acceptable. Once the reagent and water are added, invert the cuvette five times to mix.
  • Using a microfiber cloth, wipe the cuvette to remove any oils or fingerprints from the glass. Then, place the cuvette into the checker and close the lid, making sure it is completely closed. It is important to make sure that the lid is completely closed for an accurate reading.
  • Press the button. Once the screen shows "Add C2", remove the cuvette from the meter.
  • Add 0.1mL of sample. For best accuracy, use the supplied 0.1mL pipette. Note: To use the Hanna Instruments Micropipette, first attach the pipette tip. Push the button to the first "stop", and then immerse the tip into the sample. Slowly release the button to its original position. Then, wait two seconds to catch any drops before dispensing the sample into the cuvette to the second "stop".
  • Once the sample is added, add one packet of reagent B to the sample. After that, cap the cuvette and shake vigorously for 15 seconds. Wait 15 seconds for bubbles to dissipate.
  • Wipe the cuvette of any oils and fingerprints, and place back into the meter. Press the button; The meter will directly display the concentration of calcium in ppm.


  • The Benefit of Testing for Calcium

    Calcium is an essential ingredient to a healthy and functional reef aquarium. Corals and coraline algae require calcium for calcification and growth, so much so that an aquarium stocked with these organisms require regular calcium supplements in order to maintain healthy levels. A variety of commerically available supplements exist, from calcium salts to buffered calcium supplements, which raise both calcium and alkalinity. Many aquarists set up a regular supplementation schedule to maintain proper calcium levels. However, regular calcium monitoring is crucial to a healthy reef aquarium, even if such a system is in place. This is because as corals and coraline algae grow and mature, their requirements for calcium tend to increase. As a result, the growth of the aquarium might outpace the calcium supplementation regimen. The ideal range for calcium in a healthy reef aquarium is between 380-450ppm. Values below 380ppm may slow the growth of corals, whereas high levles of calcium (>500ppm) puts the tank at risk for calcium carbonate precipitation (limestone formation).

    The Limits of Traditional Color-Change Test Kits

    Many test kits on the market rely on a color change that needs to be judged by eye. These are notoriously difficult to use, especially in the lower ranges. The Hanna Marine Calcium Checker® HI758 bridges the gap between simple chemical test kits and professional instrumentation. The one-button design makes testing for calcium a cinch to use.

    Comments: A very useful and easy to use product,the instructions are clear and simple to understand. Much easier than the test kit I was using,digital results are so much nicer than counting drops or choosing colors. I don't think having to zero the unit each time is an issue,since each test is separate to begin with-opinion. For the price,a super device,I wish I'd have bought one sooner.

    Comments: A little pricey, but I think it's worth it. I have four Hanna tests and I like all of them. I have used Red Sea and Salifert tests and I prefer the Hanna tests. Hanna tests also appear to be more accurate.

    Comments: My girlfriend and I see colors different, making testing with standard kits very unreliable. With Hanna, we can now get the same result when testing.
