What is a Colorimeter?

A colorimeter is a measuring device commonly used in the colorimetric method. It usually measures the transmittance and absorption of light of a certain wavelength, and is also called a spectrophotometer. * Colorimetric method: A method in which a special reagent is added to various test samples to develop a color, and the change in the color itself or the difference in color intensity is compared to determine the density. In water quality surveys, it is used for residual chlorine concentration measurement, pH measurement, turbidity measurement, residual nitrogen measurement, oxygen concentration measurement, etc. In addition, it is used in the field of scientific research to accurately determine the concentration of samples.

Application of Colorimeter

In general water quality inspection, a special reagent is added to the collected water to develop color, which is used for precise measurement of the following items. Residual chlorine concentration measurement pH measurement Turbidity measurement Residual nitrogen measurement Oxygen concentration measurement In air pollution surveys, it is possible to measure the concentrations of nitrogen oxides and carbon dioxide by exposing the test probe to the atmosphere, washing it with a certain amount of aqueous solution, and performing a colorimetric test of the solution. In the field of scientific research, it is used for accurate concentration determination of various samples and quantification of specific substances.
