Abstract

The invention belongs to the technical field of application of laboratory instruments and particularly discloses a PH value tester applied to laboratories. The tester comprises a casing, a hanging buckle and a groove which are formed in two ends of the casing respectively as well as a power supply, a liquid crystal display, an information processing module, an early warning module and a glass electrode which are arranged in the casing respectively, wherein the power supply, the liquid crystal display, the early warning module and the glass electrode are connected with the information processing module. The PH value tester applied to the laboratories has the benefits as follows: 1, the product is reasonable in designed structure, attractive and elegant in appearance, high in test efficiency, precision in test and long in service life; 2, during usage, the friction force with a hand is increased by the aid of a handheld part on the casing, the tester is stably picked up or placed down (that is, vibration during usage is reduced), and the safety of the glass electrode is effectively guaranteed; 3, by the aid of a fluorescent layer, the requirement for usage in an outdoor dark environment is effectively met, and the application range is wide.

Description

technical field

[0001] The invention belongs to the technical field of application of laboratory test instruments, and in particular relates to a pH value tester applied in laboratories. Background technique

[0002] The pH meter is an important tool for measuring and reacting the pH value of the solution. It uses potentiometric method to measure the pH value of the solution. Therefore, the working mode of the pH meter can not only measure the pH value of the solution, but also measure the electromotive force of the battery. In Latin, PH is the abbreviation of Pondushydrogenii, which is the activity of hydrogen ions in the substance, and the pH value is the negative number of the logarithm of the concentration of hydrogen ions. The main measuring parts of the pH meter are the glass electrode and the reference electrode. The glass electrode is sensitive to pH, while the potential of the reference electrode is stable. Put the two electrodes of the pH meter into the same soluti...
