Environmental Colorimeters

GAO’s environmental colorimeters are scientific instruments used to measure the color and concentration of a substance in a sample, typically in water or soil. They work by shining a light source onto the sample and then measuring the light that is absorbed or reflected by the sample at various wavelengths. They can detect a wide range of substances, including chemicals, nutrients, and microorganisms. They typically come with a range of pre-programmed tests for different substances, and users can also create their own customized tests.

GAO’s environmental colorimeters are composed of light source, optical sensor, display, software, and power supply.

The other common names of colorimeters are color meters, chronometers, spectrophotometers, tintometers, hue meters, spectrometers, color sensors, color quantifiers, shade analyzers, color analysis tools, chroma meters, color measurement instruments, and color spectrometers.

GAO’s environmental colorimeters typically have the following functions:

  • Color measurement - The primary function of our environmental colorimeters is to measure the color of environmental samples, such as water or soil. This allows researchers and analysts to determine the presence or concentration of specific substances in the sample that may affect its color.
  • Detection of contaminants - Changes in color can be indicative of the presence of contaminants or pollutants in the sample. GAO’s environmental colorimeters can help to detect these changes and identify the specific substances that may be present.
  • Monitoring of water quality - Water quality is often assessed based on a range of factors, including color. Our environmental colorimeters can be used to monitor changes in water quality over time and identify potential sources of pollution or contamination.
  • Research and analysis – Our environmental colorimeters are used in environmental research and analysis to help us understand the effects of pollutants and contaminants on natural ecosystems. By measuring changes in color, researchers can gain valuable insights into the health and function of these ecosystems.
