Colorimetry is the measurement of the wavelength and the intensity of electromagnetic radiation in the visible region of the spectrum. Colorimetry can help find the concentration of substances, since the amount and colour of the light that is absorbed or transmitted depends on properties of the solution, including the concentration of particles in it. 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 is able to detect the amount of light which passes through the solution under investigation. The more light that hits the photocell, the higher the current it produces, hence showing the absorbance of light. A colorimeter takes 3 wideband readings along the visible spectrum to obtain a rough estimate of a color sample. Pigments absorb light at different wavelengths.

∙ 15y agoA colorimeter is an instrument used in chemistry. It measures how much light of varying wavelengths is absorbed in a particular solution and then uses that to calculate the concentration of a known solute in the solution.

∙ 15y agoA colourimeter is an instrument for measuring the amount of light passing through a liquid. It is used for measuring concentration of coloured chemicals in solutions.
A light source creates a beam of light that shines through a sample and the amount of light transmitted, (or absorbed) is measured electronically. Different colours of light source can usually be selected so for use with different colours of solutions. The instrument is basically like a spectrophotometer except that the spectrophotometer allows selection of any wavelength of light.

What is colorimeter reading?
the reading on a colorimeter, abit obvious :S
How could a colorimeter be used in a breathalyzer test?
A colorimeter is used to measure the intensity of color. The colorimeter would detect an intensity of a blue green color. When alcohol that is present increases.
How does a forensic scientist use colorimeter?
he buys a colorimeter from eric sykes for 1 billion pounds and then eric sykes throw pound coins at you while he wipes his bum with 50 pound notes
What is colorimetric titration?
The term is sometimes applied titrations where the end point is determined by a color change- e.g. using ssy methyl orange. Sometimes the term is used when a colorimeter is used- the absorption at a particular frequency of light is used to determine the concentration- (Beers Law)
How much will ftir spectrometer cost?
It depends on what type it is; in my brother's university it's around 20,000 dollars.

What is the difference between colorimeter and turbidimeter?
What is technical difference between colorimeter and turbiditymeter
What is meant by photoelectric colorimeter?
Photoelectric colorimeter is a medical term. Essentially, it is referring to a colorimeter using a photoelectric cell and appropriate filters instead of the eye.
How does a Colorimeter work in Colorimetry?
A Colorimeter can measure the absorbency of light waves. The Colorimeter has a set of changeable filters that can show which color of light to examine for greatest accuracy.
How could a colorimeter be used in a breathalyzer test?
A colorimeter is used to measure the intensity of color. The colorimeter would detect an intensity of a blue green color. When alcohol that is present increases.
How do you use a colorimeter?
we can use colorimeter for quantitative analysis of a specific substance which absorb light in the visible region.
How does colorimeter work?
By colour base
Who discovered the colorimeter?
It is not something that was discovered, it was invented. One of the most popular designs is the Duboscq colorimeter which was invented by Jules Duboscq in 1870.
How would you calibrate a colorimeter?
A colorimeter is simply a sensor of color. The instrument is normally labelled clearly for easy use by new users.
How many filters are present in colorimeter?
Typically a colorimeter has three filters. However, this can change depending on the company and type of colorimeter. For example our Gamma Scientific tri-stimulus colorimeter uses four extremely stable colored glass filters in conjunction with high quality silicon photodiodes for increased accuracy. This is done to more accurately match the CIE standard observer functions. These resources may be helpful if you have further colorimeter questions:
Why you are using blank in colorimeter?
we are using blank because if we are not inserting anything in colorimeter and keeping it open then the light from the surrounding may affect it's absorbance causing damage
