Hanna HI758 Calcium Colorimeter Marine Checker

Hanna HI758 Calcium Colorimeter Marine Checker is used to accurately check the calcium level in reef tanks.

Accurately check your reef tank's 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

The pipette is spring-loaded and will allow you to retrieve and dispense 100 µL. Just attach the pipette tip, and press the button down until it stops the first time. Then place the tip into your tank water sample and slowly let the plunger spring back up.
