At present, there are many methods for measuring water quality detectors, but some people can easily confuse these methods in daily life. In particular, many people do not know the difference between colorimeter and spectrophotometer. The analysis of light gives the parameters, but there are some differences in the structure and detection principle. In principle, the colorimeter mainly determines the water quality parameters through the three-color value of the light wave, while the spectrophotometer is the pollution through the water quality. Wavelength analysis of the reflectance of the object is a parameter of water quality. The spectrophotometer is structurally complicated. Therefore, everyone should choose according to their own needs when purchasing.
Colorimeter Water Quality Tester Features:
Colorimeters are designed to perform analysis of physical samples by mimicking human eye, brain perception. In other words, its design is based on the way of analyzing the color of water. The colorimetric information is extracted into three color values ​​to produce objective color data by using a set of light sources and a CIE 10 degree standard viewer combination and isolating a wide band three color absorption filter. These parameters can be compared to the standard if needed.
application:
The colorimeter is very accurate and is ideal for measuring chromatic aberrations as well as routine comparisons of similar colors. But they are very important for quality control. Disadvantages: Although colorimeter can produce highly accurate color measurements, they do not recognize the strength of isomers or colorants, are not suitable for color formulation, and cannot be used under variable source observer conditions.
Spectrophotometer water quality detector features
A spectrophotometer is an instrument that performs physical sample testing of water quality through full-spectrum color measurement. By wavelength-by-wavelength spectroscopy of water reflectance, absorbance or transmittance characteristics, accurate data can be generated that is beyond the human eye. And the spectrophotometer can also be used to calculate physical colorimetric information.
Applications: Spectrophotometers offer greater flexibility and versatility than colorimeter, in part because they offer a variety of light source observer combinations that can be used in a variety of geometric layouts (including 45° / 0° and d / 8°) Work under. The spectrophotometer is therefore capable of measuring metamerism, identifying colorant intensity, analyzing a wide range of sample types, and allowing the user to choose between including or not including specular reflection to account for geometric properties. Full-spectrum analysis also provides higher specificity and may identify smaller color differences in the colorimeter. Spectrophotometers are ideal for a wide range of applications in the research and development phase, as well as quality control throughout the production process. Disadvantages: The principle of the spectrophotometer is more complicated, which makes some instruments with relatively simple cost unusable. Although today's technology has made it a better user experience, not all water quality testing requires its function, especially sometimes Some users' needs can be met by a colorimeter. Ok, the difference between the colorimeter and the spectrophotometer of the water quality tester.
