A laboratory colorimeter, also referred to as a digital colorimeter, is an instrument used to measure the absorbance of wavelengths of light at a particular frequency (color) by a sample. Digital colorimeters are widely used across different work areas including, environmental testing, clinical diagnostics, pharmaceutical analysis, and biochemistry. In particular, a portable colorimeter can be used for on-site environmental analyses. Similar to
spectrophotometers, laboratory colorimeters are used to determine the concentration of a known solute in a sample since the concentration of a solute is proportional to the absorbance. The wavelength filter used is very important since the wavelength of light that is transmitted by the colorimeter has to be same as that absorbed by the sample.
