[0002] A pH meter is a precision instrument widely used in laboratories, industry, and environmental monitoring. It is primarily used to measure the pH value of a solution. Patent publication number CN204679445U discloses a pH meter comprising a pH meter body and a measuring electrode. The pH meter body is provided with an operating button and an electronic display screen on one side thereof, a heating plate is provided on one side thereof, and a bracket is provided on one side thereof. The upper end of the bracket is connected to the measuring electrode via an elastic buckle. The application describes a common pH meter that can detect the pH value of a sample by inserting the measuring electrode into a beaker containing the sample.

[0003] However, when the pH meter in the above patent is actually used, it is necessary to first insert the measuring probe into the beaker containing the liquid to be tested, and then tighten the bolt to limit the position of the measuring probe after insertion. After the test is completed, the tightening bolt needs to be loosened again to pull out the measuring probe, which is relatively inconvenient. It is impossible to quickly limit the position of the measuring probe after insertion or removal during actual use, which reduces the convenience of use and brings inconvenience to the detection work. Therefore, the utility model proposes a new pH meter. Utility Model Content
