Instrument is one of the means to measure, display and control various physical quantities and chemical parameters, and its application range is very wide. The instrument is mainly composed of measuring components, signal converters, signal processors and displays. Different types can be designed according to different application requirements.

In general, the instrument is divided into pointer, digital and graphical display and other types. Among them, the pointer meter is just like the traditional pointer meter, which displays the measured value through the position of the pointer, and is widely used because of its simple operation and reliability. Digital instrument can be measured in digital form, higher accuracy, is the more common type of instrument used in the field of laboratory and industrial automation control. The graphical meter presents the measured value through the LCD or OLED screen, which has the advantage of being more clear and intuitive. The use of

instruments also requires different treatments according to different types. Pointing instruments generally require maintenance such as scale adjustment and bulb replacement, while digital and graphical instruments rely more on software (such as operating systems and control programs) for calibration and maintenance. Therefore, the selection, use and maintenance of the instrument need to be considered according to the actual situation.

In short, the instrument is an indispensable tool in the development of modern science and technology, and its contribution to laboratory experiments, industrial production, environmental monitoring and other fields is self-evident. Through this article, readers can have a more comprehensive understanding of the basic knowledge and application methods of the instrument in order to better use and maintain the instrument in actual work and research.
