Description

Technical Field

[0001] This utility model relates to the field of pH meter technology, and in particular to a portable pH meter. Background Technology

[0002] A pH meter is an instrument used to measure the acidity or alkalinity of a solution. It is a common analytical instrument widely used in agriculture, environmental protection, and industry. There are various types of pH meters on the market, including portable and benchtop pH meters. Portable pH meters are powered by DC and can be taken to the field.

[0003] However, existing technologies still have shortcomings. Portable pH meters in the current technology are generally of fixed length, which makes it inconvenient to insert them into taller containers for testing, and they are not convenient to operate, thus failing to meet the needs of practical work.

[0004] Therefore, we propose a portable pH meter to solve this problem. Utility Model Content

Then, pressing the button starts the motor, which drives the first turntable to rotate. The rotation of the first turntable drives the second turntable to rotate via the chain. The rotation of the second turntable drives the threaded rod to rotate, which in turn moves the mounting ring. The movement of the mounting ring causes the pH meter body to move away from the interior of the shell, extending the pH meter body and making it more convenient for operators to use, thus improving usability. In this utility model, a portable pH meter is provided. By setting up a slide, a fixing block, a screw, and a pH meter body, the pH meter body is placed inside the mounting ring during installation.
