Colorimeter vs. Spectrophotometer: What's the Difference?
Edited by Huma Saeed || By Sumera Saeed || Updated on October 27, 2023
A colorimeter measures color based on human perception, while a spectrophotometer measures light intensity across a spectrum.
Key Differences
A colorimeter is an instrument that measures the absorbance of particular wavelengths of light by a specific solution. A spectrophotometer, on the other hand, is an instrument that measures the intensity of light across a broad spectrum.
