Freshwater
Alkalinity Checker® HC - HI775
The
Hanna Freshwater Alkalinity 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 Freshwater Alkalinity 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
HI775 Checker® HC (Handheld Colorimeter) provides a simple, accurate and
cost-effective way to measure alkalinity. Present in varying
concentrations in freshwater bodies, alkalinity, from carbonate and
noncarbonate salts, provides a buffer against drastic pH changes in water.
Used in the drinking water treatment process, the concentration of
alkalinity dictates which chemicals are used and at what volumes, as well
as protecting finished, potable drinking water in the distribution system.
If being used to test samples where chlorine is present the HI93755-53
Chlorine remover is available so that any possibility of a chlorine
interference is avoided. Designed as a more accurate alternative to
chemical test kits, the HI775 provides quick, accurate results in four
easy steps:
