Description

Technical Field

[0001] The utility model relates to the technical field of colorimetric devices, in particular to a Hazen color visual colorimetric device. Background Art

[0002] Visual colorimetry is a conventional method for determining concentration, limit, and color. It is widely used in routine analytical testing where accuracy requirements are not high because of its simple equipment, easy operation, high sensitivity, and no requirement for the colored solution to strictly obey Beer's law.

[0003] Common inorganic ions and many organic compounds can be measured directly or indirectly by visual colorimetry. During colorimetry, a colorimetric tube containing the colorimetric solution to be tested and a series of standard solutions of different concentrations are placed on a colorimetric tube rack. By repeatedly comparing and observing the color differences, the colors are sorted according to the depth of the colors, and finally the concentration or chromaticity of the target ion or compound in the solution to be tested is determined using the pinch criterion.

[0004] When in use, the traditional colorimetric device illuminates the solution in the colorimetric tube through a light bar. However, the colorimetric device currently used does not have a corresponding shielding device around the colorimetric tube during detection, which causes the surrounding side light to be absorbed into the colorimetric tube from the side, thereby causing errors in the final detection results, reducing the detection effect, and being inconvenient to use.
