What is a Colorimeter?

A Colorimeter measures light absorbance at a particular wavelength.g

The term photometer and colorimeter are often inter-changed.g

The term ‘photometer’ includes instruments that can measure scattered light intensity, absorbance ormeasure scattered light intensity, absorbance or fluorescence.

A spectrophotometer measures light absorbance acrossA spectrophotometer measures light absorbance across multiple wavelengths per measurement.

How does a colorimeter work?

Beer’s Law Simply stated:

There is a logarithmic relationship between the light g p gabsorbed when passed through a colored medium to

the amount of colored substance in the light’s path and the length of that path.the length of that path.

How does a colorimeter work?

The amount of light passed through a colored medium can be expressed as eithermedium can be expressed as either Absorbance or as % Transmittance

YSI uses absorbance but provides a direct readout measurement.

Summary

Light passes through a reacted sample and is absorbed in amounts proportional to the p p

concentration of the analyte you are testing.

The colorimeter measures the absorbance andThe colorimeter measures the absorbance and displays it as a concentration.
