[0025] It should be noted that by pulling out the pull-out block 407 and placing the test paper soaked in the solution inside the placement slot 408, the colorimetric test paper placed inside the placement slot 408 can be placed inside the placement box 406. The color can then be judged by combining the color inside the comparison box 409, thereby improving the ease of use of the standard colorimetric card.

[0026] according to Figure 4 As shown, the observation assembly includes a comparison box 409 connected to a fixed rod 404, a light-shielding ring 410 connected to the comparison box 409, a limiting slide rail 402 movably connected to a mounting plate 401, a splicing strip 411 connected to the limiting slide rail 402, and a lifting handle 412 connected to the splicing strip 411.

[0027] It should be noted that the position of the comparison box 409 is adjusted by connecting the mounting plate 401 and the limiting slide rail 402.

At the same time, the sliding connection method also prevents the entire standard colorimetric card from becoming unusable if a single colorimetric block 2 is damaged.

[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
