> Colorimetry
Colorimetry is defined as the
measurement of a parameter whose concentration
is proportional (directly or inversely related)
to color intensity after the addition of known
volume of reagent(s). Different chemical substances
absorb different and varying visual light
frequencies. Since the absorbance of a substance
is proportional to its concentration i.e.,
a more concentrated solution gives a higher
absorbance reading, therefore the concentration
of a known solute can be measured using a
colorimeter.
Eutech’s latest range of portable
waterproof colorimeters measure Chlorine (Free
and Total), Cyanuric Acid, pH, Chlorine Dioxide,
Bromine and Ozone. The applications include
water analysis in swimming pools, spas, public
utilities, industrial wastewater plants, municipal
water, treated water, water conditioning systems
and paper and pulp mills.
The effectiveness of the disinfectants
used depends on your system’s overall water
chemistry, and not just on the disinfectants’
concentrations alone. Click

of each parameter.
