Description

Technical Field

[0001] The utility model relates to the technical field of acidity detectors, and more specifically, to a pH acidity detector. Background Art

[0002] A pH meter is an instrument used to measure the acidity or alkalinity of a solution, and is commonly used in chemical laboratories, environmental monitoring, food processing, etc. It can accurately measure the acidity or alkalinity of a solution and display the result in digital form.

[0003] Publication No. CN220289573U discloses an acidity meter for food testing. The clamping ring used for fixing the testing rod in the acidity meter in the cited document cannot be applied to the fixing of testing rods of different sizes, and the versatility is insufficient. When using testing rods of other sizes, the clamping ring needs to be disassembled and replaced, which is a waste of time. A handle is provided, and by pressing the handle downward, the testing clamping plate will be driven to move to both ends, and the testing rod will be clamped in the middle of the testing clamping plate. When the handle is released, the elastic force of the spring will make the testing clamping plate clamp and fix the testing rod, so that testing rods of different specifications can be fixed. The versatility is good, and the lifting plate is prevented from rotating in a circle with the threaded rod, and the vertical displacement of the lifting plate up and down is guaranteed. The lifting plate can be limited by the limit plate when moving up and down, and the testing rod can perform acidity detection on the food solvent in the detection cup, and can perform a single detection or simultaneously perform acidity detection on multiple foods.

[0004] During the use of the acidity tester, it is inconvenient to stir and mix the solution, and the acidity of each layer in the solution may be different, which affects the accuracy of the test result. At the same time, the test stick is erected on one side of the test host, which takes up more space. At the same time, it is exposed to the outside for a long time when not in use, which is inconvenient to fold and store and move for transportation. At the same time, the protection of the test stick is insufficient. Utility Model Content
