Problems solved by technology

[0002] At present, the method used for roughly measuring the pH value in the field basically uses pH test paper for testing. The key product can be roughly tested. This method is not convenient for the protection of the PH value standard color card. If the phenomenon occurs, we can only make more backups, which increases the backup capacity from the surface, and takes up a lot of space when there are too many

Embodiment 1

[0019] Such as figure 1 , figure 2 , image 3 As shown, the color comparison card with lock for PH test paper comparison includes a standard color comparison card 2 for pH test paper comparison and a vertically placed fixing plate 5, and a chute is vertically opened on the left side of the fixing plate 5 6. There is a slider 12 that can slide freely up and down in the chute 6, and a groove 9 for inserting PH test paper is horizontally arranged on the side of the fixed plate 5 corresponding to the chute 6, and the groove 9 is connected with the slider 12 through the bolt 8. Fixed together, the standard color comparison card 2 is made up of several standard color comparison card blocks of different colors, and the standard color comparison card blocks are vertically arranged on the fixed plate 5 on the right side of the chute 6 at equal intervals, and set on the fixed plate 5 There is a transparent transparent plate 3 used for the protection of the standard color comparison c...

Embodiment 2

[0023] A change is made on the basis of Example 1, and the distance between the adjacent standard color blocks is changed to 6mm. Others are the same as embodiment one.

Embodiment 3

[0025] A change is made on the basis of Example 1, and the distance between the adjacent standard color blocks is changed to 7mm. Others are the same as embodiment one.

Abstract

The invention relates to a colorimetric card board with lock for PH test paper comparison, which belongs to the technical field of pH test paper colorimetric equipment, which includes a standard colorimetric card for PH test paper comparison and a vertically placed fixing plate, which is used for fixing There is a chute vertically on the left side of the plate, and a slider is arranged in the chute, and a groove is horizontally arranged on the side of the fixed plate corresponding to the chute, and the groove is fixed with the slider by bolts. The standard colorimetric card block is composed of two standard colorimetric blocks of different colors. The standard colorimetric block is vertically set on the fixed plate on the right side of the chute, and the corresponding slider is provided with a sliding mechanism for sliding up and down in the chute. There is a baffle for pressing the pH test paper at the notch. The invention can well protect the standard color comparison cards from being damaged when used, does not need to reserve a large number of standard color comparison cards, and is also very convenient for comparison.

Description

technical field [0001] The invention relates to a colorimetric card plate with lock used for pH test paper comparison, and belongs to the technical field of pH test paper colorimetric equipment. Background technique [0002] At present, the method used for roughly measuring the pH value in the field basically uses pH test paper for testing. The key product can be roughly tested. This method is not convenient for the protection of the PH value standard color card. When the phenomenon occurs, we can only make more backups, which increases the amount of backups, and takes up a lot of space when there are too many. Contents of the invention [0003] In view of the above problems, the present invention provides a colorimetric card with lock for pH test paper comparison, which has a simple structure and can well protect the standard colorimetric card from damage during use, ensuring the comparison accuracy and being easy to use. It is very convenient, there is no need to reser...
