The colorimeter is an instrument used to measure the color of a substance, using the RGB color system. This system uses three primary colors: red, green, and blue. Similarly, it measures the intensity of each and then combines them to create a color. It has an accuracy of 0.01%. This is very useful for chemists, as they can use the colorimeter to measure small amounts of substances. The colorimeter is also used in medicine, where doctors use equipment to measure the color of blood and other body fluids to detect diseases and medical conditions. It is a very useful instrument that is used in many fields. It is precise, easy to use and available in many sizes and shapes.

That said, the Kalstein colorimeter states that the absorbance of a solution is proportional to the concentration of the solution, which consists of a light source, a filter, a detector and a reading device.


Types of Colorimeter that a lab may need


YR053442 // YR053445 is Kalstein using autonomous core technology research and development of A portable light color difference instrument, is the high level in spectral architecture color difference instrument, in addition to ensure accurate relative Δ E at the same time, also to ensure the accuracy of the absolute value of L, A and B for A long time, anytime, anywhere can pass the international standards and national standards of measurement.
