Description

Technical Field

[0001] This utility model relates to the technical field of pH meters, specifically to a safety protection structure for pH meters. Background Technology

[0002] A pH meter, also known as an acidity meter, is an instrument used to measure the acidity or alkalinity of a solution. The pH meter works on the principle of a galvanic cell. According to Nernst's law, the electromotive force between the two electrodes of a galvanic cell is related to both the properties of the electrodes themselves and the concentration of hydrogen ions in the solution. There is a corresponding relationship between the electromotive force of the galvanic cell and the concentration of hydrogen ions. The negative logarithm of the hydrogen ion concentration is the pH value.

[0003] A pH meter is a common analytical instrument widely used in agriculture, environmental protection, and industry. Normally, when measuring the pH value of a liquid, the probe is inserted directly into the liquid, and after the measurement is completed, the probe is pulled out of the liquid. Then, the liquid on the probe is cleaned. However, when not in use, the probe is usually exposed, which allows a lot of dust to accumulate, making subsequent testing inconvenient and prone to errors. Alternatively, some existing models use caps to cover the probe, but the probes can be placed arbitrarily, making it difficult to standardize their use, and it is easy to forget to put the cap back on.
