Tube type thermometer, the contrast of pointer thermometer and digital thermometer

We use a thermometer to accurate judgment and measuring temperature. In science and technology with each passing day today, there are numerous kinds of thermometer for us to choose, but at the same time we should pay attention to the correct method of use, understand the characteristic of the thermometer, facilitate better use. Glass rod thermometer is a typical tubular thermometer and a thermometer is the most widely used, its simple structure, convenient use, high accuracy and low price, can be divided into the industry, with three standards and lab, widely used in chemical production, machinery manufacturing, and various laboratories of temperature measurement. Most of pointer thermometer for bimetallic thermometer, is a kind of measuring instrument in the field of low temperature detection, can be directly measured in the process of various production - 80 ℃ ~ + 500 ℃ within the scope of liquid, steam and gas medium temperature. Its advantage is the pointer to display temperature, intuitive and convenient; Safe and reliable, long service life, the structure form is varied, can satisfy different requirements; Shortcoming is low accuracy, convenient using, display not intuitive. Compared with digital display thermometer, also called electronic thermometer, can accurate judgment and measuring temperature, with digital display, is a kind of high precision, good stability and strong applicability of new field temperature display, are widely used in various industrial and mining enterprises, universities, research institutes, etc.
