Description

Ideal for salt water aquariums and coral reef tanks. Designed to measure calcium in reef tanks, the Hanna Calcium Checker is perfect for corals and marine life. This Checker®HC from Hanna instruments is supplied with reagents for 25 tests.

Corals need an adequate level of calcium in the water to support healthy growth: if levels are too low, corals cannot form their skeletons; if levels fluctuate too much or too quickly, growth can become impaired. The more precise and stable the levels, the better the results. With regular, precise monitoring, fluctuations in levels can be quickly corrected, giving your corals the best chance of success.

Key Features:

Test Results in 4 Easy Steps
Quick results from a single button in 4 easy steps. Place 1ml of reagent A and 9ml of deionised water sample inside the vial. Zero it in the Checker. Add 0.1ml sample to be tested and 1 packet of reagent B. Return the now full vial to the checker. Press the button and read the result.

More Accurate than Chemical Test Kits
The checker uses am adaptation of the zincon method. The result given is accurate to 1 ppm between 200 to 600 ppm. Most chemical test kits on the market are only accurate to 5 ppm.

Hand-held Portable Design
Small compact size with a single button and powered by only one AAA battery (included) makes these Checkers from Hanna Instruments incredibly versatile and portable. Perfect for aquarists, aquaculturists, fish keepers, and even scientists in the field.

Orders containing live plants will take up to 2 weeks to arrive. We take a week's worth of customer orders and then inform the plant farms of the specific quantities we need to fulfil that week's order to avoid wastage.
