The thermometer you use for? What kind of more accurate?

A lot of people in the use of the thermometer, will consider what kind of thermometer would be better to use? What kind of thermometer is not only to use and more accurate? The primary purpose of this is also a lot of people use the thermometer! With the development of high-tech, more and more electronic equipment, there are a lot of articles for daily use are in same replaced by electronic products, but really useful electronic products? It's not certain, such as thermometer, electronic thermometer but no mercury thermometer to use! Here are to say to you about why mercury thermometer than electronic thermometer works! As you know, we first use the thermometer is the mercury thermometer, mercury thermometer is made up of mercury is proportional to the temperature of the thermal expansion to work. Mercury is very stable, closed its thermal expansion coefficient is a constant in the thermometer. Electronic thermometer is the thermal sensor for temperature of thermoelectric emfs. Due to the thermal sensor drift problem and the problem of cold junction compensation electronic thermometer, so the level is not high accuracy may be slightly worse. Especially the electronic thermometer will under the influence of ambient temperature and extremely, electronic thermometer with mercury thermometer calibration. Mercury thermometer, of course, is accurate. Through the introduction of the above is to have a better understanding of thermometer, so not all electronic products is good, and the mercury thermometer is more accurate than electronic thermometer! If we use thermometer, to achieve accurate temperature, mercury thermometer is the best choice, you choose the right?
