Description

Technical Field

[0001] The utility model relates to the technical field of portable pH test paper clips, in particular to a portable pH test paper clip. Background Art

[0002] As we all know, test paper is a type of paper that has been impregnated with chemicals during the experiment and can detect the presence of certain substances in liquids or gases through its color changes. When using various types of test paper for testing, the test paper will change color in different ways, and the results will be obtained by comparing with the standard control color. pH value is a commonly measured parameter in various chemical tests. When the accuracy requirements are not high, standard pH test paper is generally used for measurement.

[0003] The existing pH test paper does not have a professional stand when measuring. The only way is to hold the pH test paper by hand, drop the test solution onto the test paper, and then find a standard pH test paper reference table for comparison. It is more troublesome to use. Therefore, we propose a portable pH test paper clip to solve the above problem. Utility Model Content
