A colorimeter is used to measure the absorbance of specific wavelengths of light by a particular solution. This is used to determine the concentration of a known solute in a solution using Beer's law. This law states that the concentration of a solute is proportional to the absorbance.
Colorimeters are basically used to estimate colored compounds and are indicative of specific levels of compounds in the solution. From a clinical point of view, knowing the levels of certain compounds in body fluids is imperative for accurate diagnosis of an ailment. Consider glucose, which is clinically estimated by colorimetric method and is indicative whether of not a person is suffering from Diabetes, amongst other indications.
we can use colorimeter for quantitative analysis of a specific substance which absorb light in the visible region.
A colorimeter is simply a sensor of color. The instrument is normally labelled clearly for easy use by new users.
1. Densitometer A densitometer is a type of colorimeter that helps control color by measuring the darkness and lightness of a printed material during the printing process. A densitometer evaluates color by placing a test strip or print control strip along the edge of a proof. Color Temperature Meter Photographers and cinematographers opt for a color temperature meter, a type of colorimeter, to balance the color in photos and cinematograph's flash and continuous light. § Viscosity Meter Precise Lab & Process Viscometers. Get Engineering Tristimulus Colorimeter A tristimulus colorimeter measures color from primary light resources such as light signals, lamps, filters, displays and monitors. Spectroradiometer A spectroradiometer is a type of colorimeter that measures the intensity and irradiance of color.
A colorimeter is a scientific instrument that measures the intensity of light passing through a pure sample. In biology, colorimeters are used to monitor the growth of cultures. As the culture grows, the growing medium becomes more cloudy and absorbs more light.
In nontechnical and simple terms, in colorimeter particular band is selected and not the particular single wavelength. instead in spectrophotometer single wavelength is selected. also in colorimeter the filter is used whereas in spectrophotometer monochromator or prism is used.
main equipments are microscope colorimeter centrifugal machine hot air oven incubator etc. and also may be clinical chemistry analyzer.
the reading on a colorimeter, abit obvious :S
What is technical difference between colorimeter and turbiditymeter
Photoelectric colorimeter is a medical term. Essentially, it is referring to a colorimeter using a photoelectric cell and appropriate filters instead of the eye.
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.
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.
we can use colorimeter for quantitative analysis of a specific substance which absorb light in the visible region.
By colour base
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.
A colorimeter is simply a sensor of color. The instrument is normally labelled clearly for easy use by new users.
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:
Cognitive psychology has future applications when more data in the function of the human mind is revealed by clinical /medical science & research specially in learning/abnormal behavior with clinical applications.
