Chromaticity refers to an indicator for quantitative color detection in natural water or treated water of different types. If the color intensity of water is to be detected, the “COL-8000- Online Water Quality Color Intensity Monitor” should be used. Among them, the colors that natural water often shows include light yellow, light brown, yellowish green, etc. The main cause of these colors is substances such as humus, organic matter or inorganic matter that dissolve in water.

For example, when water bodies are polluted by industrial wastewater, they will show different colors. This color can be divided into two types: true color and surface color. True color is caused by dissolved substances in water, that is, the color after the suspended solids in water are removed. However, surface color is the color produced when the suspended solids in water are not removed, and the degree of this color is called chromaticity.

Some Requirements Regarding Chromaticity:

The color of domestic drinking water should be less than 15 degrees.

The color intensity of water used in the papermaking industry should be less than 15 to 30 degrees.

The color intensity of water used in the textile industry should be less than 10 to 12 degrees.

The chromaticity of the dyeing water should be less than 5 degrees.

How Can the Color Intensity in Water be Detected?

The Hangzhou Mudi COL-8000 water quality color Online monitoring instrument is a fully automatic monitoring instrument controlled by an embedded system, which is suitable for real-time monitoring of the total color of many water qualities. The working principle is that after the sample is filtered through the membrane, it is pumped to the measurement cell. The color value of the water sample is calculated based on the change in the water sample’s sensitivity to light. For some water samples with a large color intensity, it can be automatically diluted at a reduced cost, and the detection range of water color intensity can be expanded through multiple dilution.
