What are the differences between a colorimeter and a spectrophotometer in terms of their functionality and applications?

A colorimeter measures the intensity of a specific color in a sample, while a spectrophotometer measures the entire spectrum of light absorbed or transmitted by a sample. Colorimeters are simpler and more affordable, commonly used for basic color analysis. Spectrophotometers are more advanced, providing detailed information on the composition and properties of a sample, making them suitable for a wider range of applications including chemical analysis and quality control in various industries.
