Colorimeter vs. Spectrophotometer

Colorimeternoun

Any of various instruments designed to determine the color of something, by comparison with standard colors or by spectroscopy.

Colorimeternoun

(analytical chemistry) An analytic instrument that estimates the concentration of a substance in a sample by measuring its color against the solution's complimentary color.

Colorimeternoun

An instrument for measuring the depth of the color of anything, especially of a liquid, by comparison with a standard liquid.

Colorimeternoun

a measuring instrument used in colorimetric analysis to determine the quantity of a substance from the color it yields with specific reagents

Spectrophotometernoun

(physics) An instrument used to measure the intensity of electromagnetic radiation at different wavelengths.

Spectrophotometernoun

An instrument for measuring or comparing the intensities of the colors of the spectrum.

Spectrophotometernoun

An analytical instrument for measuring the degree of absorption of light at different wavelengths by a chemical substance. A specific pattern of absorption intensities at a series of wavelengths is a characteristic of each different chemical substance.

Spectrophotometernoun

a photometer for comparing two light radiations wavelength by wavelength
