What is colorimeter used for?

A colorimeter is an instrument that compares the amount of light getting through a solution with the amount that can get through a sample of pure solvent. A colorimeter contains a photocell which is able to detect the amount of light passing through the solution under investigation.

A common method for testing how much of a substance is in the water is to run a Colorimetric test. A colorimetric test is a test which forms a color. The amount of the color is then measured. In most tests the more color formed, the more of the test substance there is in the water.

Colorimetry, measurement of the wavelength and the intensity of electromagnetic radiation in the visible region of the spectrum. It is used extensively for Identification and determination of concentrations of substances that absorb light.

Principle of Colorimeter is that Coloured compounds can absorb a certain wavelength of light when monochromatic light is passed through them. The working of a colorimeter is based on the concept of Beer-Lambert’s law.

Types of Colorimeter

1. Spectrophotometer: This is the most accurate type of colorimeter and can be used to measure the spectral reflectance of a surface. 2. Densitometer: This type of colorimeter is used to measure the density of a material.

A colorimeter “sees” color like the human eye and can determine a color’s location in color space by quantifying the values of red, green, and blue. A spectrophotometer offers more accurate color measurement by capturing color across the entire visible spectrum and filtering the light into very narrow bands of color.

Colorimeter is an instrument that measures the amount of transmitted rays of light absorbed by a specific solution. However, a spectrophotometer measures the intensity of light as a function of colour or wavelength of light by the transmittance level.

Colorimeters generally measure transmittance (a linear scale from 0-100%) as well as absorbance (a logarithmic scale from zero to infinity). The displayed value, however, is usually either Mg/L or ppm Which are calculated from measured values.

In chemistry, the colorimeter is a device that determines the absorbance of a solution at a particular frequency (color) of visual light. Colorimeters make it possible to determine the concentration of a known solute since it has been proportional to the absorbance.

Reflected color can be measured Using a spectrophotometer (also called spectroreflectometer or reflectometer), which takes measurements in the visible region (and a little beyond) of a given color sample.

A colorimeter can measure the absorbency of light waves. During colour measurement The change in the intensity of electromagnetic radiation in the visible wavelength region of the spectrum after transmitting or reflecting by an object or solution is measured.

It is also used by The merchants who deal in a diamond As they use it to measure the properties of the diamonds and identify whether they are real or not. A colorimeter can analyse the skin tone of a person and the tooth colour and thus helps to diagnose dental and dermal diseases that one may be experiencing.

A colorimeter is able to measure Light absorbance (how much light is absorbed) or light transmission (how much light passes through) A substance. Colorimetry can be used in any enzyme-catalysed reaction that involves colour change.
