Redesigned with new 100 µL Pipette

Accurately check your reef tanks calcium level with the Hanna HI758 Calcium Checker.

Three simple steps to results. The Hanna Calcium Checker bridges the gap between simple chemical test kits and professional instrumentation. Accurate, affordable and easy to use. First, zero the instrument with your water sample. Next, add the reagent. Last, place the vial into the Hanna Calcium Checker, press the button and read the results. Done.



Easier to use and more accurate than chemical test kits.

Tips for accurate results:

Use Hanna HI70436 Deionized Water
Make sure testing vials are clean of any debris
Vials must be dry on the outside with no fingerprints
Violent shaking will cause microbubbles that can affect the reading
Do not let the sample sit too long before taking a reading

Then place the tip into your tank water sample and slowly let the plunger spring back up. Move the pipette to your testing vial, and press the plunger down to the first stop to dispense the liquid it took in.
