Using a precision colorimeter is important because it is the only way to measure color accurately. Human eyes cannot measure color accurately, so a device is needed to measure color.
The colorimeter is a very sensitive measuring instrument, and can measure the absorbance of light over a very wide range of wavelengths. Most colorimeters can measure absorbance in the range of ultraviolet, and some can measure absorbance in the range of infrared.
It can be used to measure the color of a solid, liquid or gaseous sample. The precision colorimeter is commonly used in laboratory and production applications, which is important in many industries, as color can be an indicator of impurities or differences in product quality. To use a precision colorimeter, illuminate the sample with white light and then measure the color of the reflected light using the instrument. Samples of different sizes, shapes and colors can be measured.
