The advantage of mercury thermometers is that they are cheaper and measure temperature relatively quickly. However, mercury thermometers are easy to be broken and leaked by children, causing potential safety hazards. In addition, mercury thermometers generally have a small scale and are difficult to identify readings for some elderly people. Electronic thermometers generally have simple digital display readings and have buzzers to prompt the completion of temperature measurement. Generally speaking, the user experience is relatively friendly. As for the accuracy of electronic thermometers, they can generally be accurate to 0.1 degrees, which is sufficient for daily use.
