Who is better? Mercury thermometer was compared with the electronic thermometer

Mercury thermometer invented earlier, there are many use, not to mention the field of application, it must be very broad. And the history of the electronic thermometer is short, but the momentum is better, mainly because of the inside of the mercury thermometer mercury harmful to human body, more and more people choose the electronic thermometer. One is the electronic thermometer readings more convenient than mercury thermometer. But in terms of accuracy, electronic thermometer will be slightly smaller. The nature of the mercury in the mercury thermometer is stable, thermal expansion coefficient is a constant in the confined space. And electronic thermometer is generated by thermal sensor for temperature of thermoelectric emfs, but thermal sensor drift problem and the problem of cold junction compensation, so levels high enough on the accuracy of the electronic thermometer was slightly worse. Therefore, electronic thermometer are basically with mercury thermometer calibration. In general, cannot determine two kinds of thermometer which is better, two kinds of thermometer are there are both advantages and disadvantages. Therefore, remind everybody when choosing to choose according to their needs, suitable is the best.
