YSI ColorimetersYSI ColorimetersA new line of single and multiparameter
colorimeters
March 14, 2013Presented by Laura St. Pierre
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.
YSI’s New Line of Colorimeters
2 new single parameter2 new single parameter colorimeters:
• 900 for free and total chlorine900 for free and total chlorine
• 910 for COD measurement
