Description

Technical Field

[0001] The utility model relates to the technical field of laboratory pH, in particular to a fall-proof pH meter. Background Art

[0002] The hydrogen ion concentration index refers to the ratio of the total amount of hydrogen ions in a solution to the total amount of substances, generally referred to as "PH" rather than "PH value". The hydrogen ion activity index can be determined qualitatively by using PH indicators and PH test papers, while quantitative PH measurements require the use of a PH meter. The PH meter device we use inserts several PH test tubes on the PH meter device body into the solution to be tested, and the PH value is displayed on the screen on the PH meter device body to test the PH value of the solution. The PH test tube is exposed to the outside, which may cause the PH test tube to break during use, causing the PH meter device body to fail to work.

[0003] In the prior art, when the pH meter device body is not in use, the pH test tube is exposed to the outside. There are other solution gases in the air of the laboratory. Other solution gases adhere to the pH test tube. When the pH test tube is inserted into the solution, the pH value of the test will be inaccurate, thereby affecting the observation of the tester. At the same time, the pH test tube will collide in the process of holding the pH meter device body, thereby causing it to break. Therefore, it is necessary to design and modify the pH meter to solve the problem of the pH meter contacting with other solution gases and the pH test tube breaking. Utility Model Content
