Marine
calcium Checker HC® colorimeter
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® 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.

Operation
The
HI758 Checker® HC
(Handheld Colorimeter) provides a simple, accurate and cost-effective way
to measure calcium. Required for the development of calcium carbonate
skeletons of coral reefs, calcium is a crucial component of marine waters.
Designed as a more accurate alternative to chemical test kits, the HI758
provides quick, accurate results in four easy steps:
Features
-
Easier to use and more accurate than chemical test kits
-
Dedicated to a single parameter
-
Small size, big convenience
-
Ideal for: Saltwater aquariums, aquaculture, water quality, environmental,
education
