What are the types of colorimeter?

Colorimetry is a tool for the determination of intensity and the wavelength of electromagnetic radiation in the visible range of the spectrum. It is a color measurement tool used to communicate, capture, and evaluate the color, and also broadly used to identify and determine the concentrations of color substances which absorb light.

It compares the amount of light of the solution with the pure solvent. They can work quantitatively and qualitatively for the analysis of color analytes in various applications.

The spectrophotometer and tristimulus colorimeter are the two types of colorimeters are used for color measurement.

Tristimulus colorimeters:

Tristimulus colorimeters are typically used in quality control and are consistent with determination color differences and tolerance. The tristimulus technique estimates the light reflected from the item utilizing three sensors separated to have a parallel sensitivity. 

The colorimeter can be used broadly for different applications, today has several tristimulus colorimeters are available for the manufacturing of color samples, and examination of color quality control.

Spectrophotometer:

A spectrophotometer is a tool that can measure the intensity of light as a function of color or more particularly, the wavelength of light and other sample solutions. It detects the whole range of UV (200-400 nm) as well as the visible range (400-800 nm). 

By giving the wavelength by wavelength spectral analysis of the sample absorbance or transmittance properties it gives accurate data. A spectrophotometer is easy and rapid to operate and is most generally used for the measurement of light absorption.
