Colorimeters

What is a colorimeter? A colorimeter measures the amount of light transmitted or reflected through a liquid sample.


What is a spectrophotometer? A Spectrophotometer does similar things. Except it measures wavelengths beyond the range of the visible colors into infrared and ultraviolet regions.


How do they work? Basically, colorimeters and spectrophotometers “read” a liquid sample, and give you a reading that corresponds to the sample’s color.


You can use the reading to identify chemical compounds or quantify their concentration.


Any colorimeter and its more sophisticated counterpart, the spectrophotometer, has five basic components:

The cost of a color measuring device varies hugely depending on the range of wavelengths it measures.


The applications for a colorimeter are myriad and the choices on the market are vast.


We have done the legwork for you and handpicked a list from handheld to rugged field color measurement instruments with specific applications in chemicals, petroleum, plastics, pharma and cosmetics, edible oils, and F&B.


If you perform any of these tasks on a regular basis:

  • Maintain color consistence in your liquid samples and products
  • Look for impurities or variations
  • Check color variations to identify specific processes, such as oxidation
  • Monitor sample color and its variations to measure functionality and characteristics
