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.
