An instrument is a device or device used to detect, measure, observe and calculate various physical quantities, physical components, physical parameters, etc.. Vacuum leak detector, pressure gauge, length measuring instrument, microscope, multiplier and so on all belong to instrument and meter. In practical work, we often use the instrument is divided into two categories: Automation Instrument and portable instrumentation, automation instrument refers to need fixed installation in the field of instrument, also known as the installation instrument or dial instrument installation, this kind of instrument and other equipment, to complete one or several function; portable instrument is used alone, sometimes called instruments, generally divided into two kinds of desktop and handheld. Directly contact with the body of electronic instruments, in addition to the instrument itself performance requirements more and more high, besides, the personal safety considerations have also attracted much attention. In order to ensure its safety performance, it is very important to choose electronic materials. So how to choose the electronic instrumentation applications, such as chip capacitors, capacitors, SMD resistor, SMD inductor, tantalum capacitors, electrolytic capacitors, resistors, zener diode, rectifier diode, light-emitting diodes and other electronic components. It plays an important and decisive role in improving the performance parameters of instrument and meter products.
