Detailed Description

The present invention will be further described with reference to the accompanying drawings.

The test paper color comparison device shown in the attached figures 1 to 6 comprises a bottom plate 1 and a separation tube 2, wherein the separation tube 2 is arranged on the upper surface of the bottom plate 1, a test paper detection area 4 is arranged in the tube of the separation tube 2, test paper is put in from the orifice of the separation tube 2 and is placed on the surface of the bottom plate 1, and then a solution to be detected is dripped; the outside of the separating tube 2 is provided with a color contrast area 3; a color comparison card 5 is arranged in the color comparison area 3, the color comparison card 5 is arranged on the surface of the bottom plate 1, the color comparison card 5 comprises a plurality of color blocks 6, the color blocks 6 surround the test paper detection area 4 in a surrounding manner, and color comparison between the test paper and the surrounding color blocks 6 is facilitated when the test paper changes color; the color comparison operation can be conveniently carried out within the specified time, and the detection precision is improved. It should be noted that the present invention is not limited to the colorimetric test of pH paper when measuring the pH of a solution, and can also be used for other related tests requiring color comparison.

The part of the bottom plate 1 right below the separation tube 2 is hollowed, and a test paper detection plate 8 is additionally arranged on the hollowed part of the bottom plate 1; the test paper detection plate 8 is connected with the shaft hole of the bottom plate 1 in a matched mode, and the test paper detection plate 8 rotates around a shaft relative to the turning surface of the bottom plate 1; the test paper detection plate 8 replaces the original integrated bottom plate 1 to place test paper, and the test paper can be driven to turn over through the turnover face of the test paper detection plate 8, so that the test paper can be taken out conveniently; meanwhile, the test paper detection plate 8 can be used on two sides and is convenient to clean.

The colorimetric card is characterized by further comprising a cover plate 7, wherein the cover plate 7 covers the colorimetric card 5, and parts of the cover plate 7 corresponding to the separation tubes 2 are hollowed out, so that interference influence on the tube openings of the separation tubes 2 is avoided; at this time, the color comparison card 5 is positioned between the bottom plate 1 and the cover plate 7, so that the negative effects of abrasion and solution corrosion on the color comparison card 5 can be effectively prevented.
