Overview

*Affordable electronic tester for measuring calcium in reef aquariums
*Measures aquarium calcium from 200-600 ppm w/ 1ppm resolution
*Easier & more accurate than chemical aquarium test kits for calcium

Upgrade from chemical test kits to professional instrumentation without breaking your budget. Hanna Instruments Marine Calcium Checker HC is a budget-friendly single parameter electronic tester for measuring marine calcium level. Compact handheld colorimeter delivers the accuracy of professional instrumentation at the affordable price of a chemical test kit.

Easier and more accurate than chemical test kits, Hanna Instruments Marine Calcium Checker HC provides a simple, accurate and cost effective way to measure calcium. Accurate routine measurement of calcium is essential to ensure proper calcium levels crucial for coral growth in marine reef aquariums.

Hanna Instruments Marine Calcium Checker HC measures just 2.4" x 1.5" x 3.2" high and features a range between 200 to 600 ppm with 1 ppm resolution (±6% accuracy @ 25°C/77°F of reading).

Hanna Instruments Marine Calcium Checker HC (HI758) is supplied with (2) sample cuvettes with caps, calcium reagent starter kit for 25 tests, dropper, (2) 1 ml syringes with tips, 1.5V AAA battery, instructions and quick start guide.

To obtain the highest accuracy and precision from your Hanna Marine Calcium Checker® HC it is necessary to add exactly 100 µL of aquarium saltwater to the cuvette. Any variation will result in an inaccurate reading. Use the 100 µL Hanna Instruments Graduated Pipette to help ensure precise volume of sample aquarium water necessary for accurate test results.

Hanna Instruments Marine Calcium Checker HC
Designed as a more accurate alternative to chemical test kits, the HI758 provides quick, accurate results in four easy steps:

  1. "Zero" the Checker HC as required in specific procedure
  2. Add reagent to your water sample
  3. Place the vial into your Checker HC
  4. Press the button and read the results
  5. It's that easy!

*To Zero, 1 ml of Reagent A is added to deionized/distilled water as a blank.

General Information
The Hanna Marine Calcium Checker® bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits have limited accuracy and resolution since they rely upon the human eye to discern differences in color. Professional instrumentation incorporates a light source such as an LED or tungsten lamp with a filter and a light sensing detector to precisely determine absorbance and ion concentration. Professional instrumentation offers greater resolution and accuracy but can cost hundreds of dollars. The Hanna Marine Calcium Checker HC uses a fixed wavelength LED and silicon photo detector to provide the accuracy of professional instrumentation at the affordable price of a chemical test kit. 6 month limited warranty.
