An instrument for measuring the depth of the color of anything, especially of a liquid, by comparison with a standard liquid.
Colorimeter is an instrument for measuring color the way the eye sees it.
A device used in analysis in which a fairly broad band of radiation or color, usually in the visible wavelength, is used. For example, the determination of chlorine in water by using the DPD method uses a visual comparison of samples and standards. Other testing techniques use a photometer or light detector.
A light sensitive device used for measuring color values in a way similar to the human eye
An optical instrument that measures the relative intensities of red, green, and blue light reflected or emitted from (or transmitted through) a color sample. Typically used to measure color from computer monitors.
An instrument used to measure color the way the eye sees it.
An optical measurement instrument that responds to color in a manner similar to the human eye, by filtering reflected light into its dominant regions of red, green and blue.
a measuring instrument used in colorimetric analysis to determine the quantity of a substance from the color it yields with specific reagents
a machine that measures color
a machine used to measure the light intensity and color
an instrument that can be used to determine the concentration of a solution by determining the amount of light that the solution absorbs
an instrument used for the measurement of color based on the optical comparison with standard colors
an instrument which compares the amount of light getting through a solution with
a simple three color (wavelength) spectrophotometer that uses a light emitting diode (LED) as a light source
a spectrophotometer (a device that measures light intensity as a function of wavelength) with spectral weighting functions that simulate the sensitivity of the eye's color receptors
A computerized instrument that measures the amount of power in each wavelength in a light source. See spectrophotometer (Zelanski).
An instrument for measuring the tristimulus values of color with a precise and defined response that is similar to the human eye.
An optical measuring device designed to respond to color in a manner similar to the human eye.
An instrument for measuring colour the way the eye sees colour.
A light sensitive device for measuring colors by filtering their red, green, and blue components, as in the human eye.
Apparatus optronic (optical and electronic) of measurement of the color by the analysis of the light emitted or reflected according to three channels Red, Green and Blue (sometimes more).
An electronic optical instrument used for measuring color as it is seen by the human eye.
An optical device that measures absorbance of light by filtering reflected light into regions of red, green and blue. While dedicated colorimeters do exist, most instruments actually spectro-photometers that compute colorimetric values based on spectral reflectance or transmittance curves.
An instrument for measuring color. It uses a selenium cell that can measure the relative transmission of yellow and blue light by a diamond.
Device that measures color values in relation to a specific set of standards, such as CIE. Enables measurement of differences in colors more precisely than the human eye.
This is an instrument that measures reflectance in the same manner as a densitometry.
A colorimeter (invented by Jan Szczepanik) is a device used to measure the absorbance of a specific solution. It allows the absorbance of a solution at a particular wavelength of light to be determined. The most common application of a colorimeter is to determine the concentration of a known solute.
