Comparison of mercury thermometers and electronic thermometer)

Now more common in the family is the thermometer thermometer, mercury thermometer or electronic thermometer is more popular with families, and do you know what is the difference between the two thermometer? Mercury thermometer advantages: the most common form of thermometer is the mercury thermometer, it can keep up with the mercury in the body temperature of the original position, facilitate users observed at any time. Because the structure of glass is dense, mercury's performance is very stable, so the mercury thermometer is accurate and value for the characteristics of high stability, and the advantages of low cost, no external power supply, trusted by the people, especially the medical workers. The mercury thermometer faults: mercury thermometer obvious defects, easily broken, mercury pollution may exist; This is a kind of old thermometer, experts believe that the degree of danger of mercury thermometer is very large, than people think. People put it in the mouth temperature, for example, one thousand thermometer is broken, mercury is likely to flow into the mouth, and even be swallowed. The mercury as soon as possible in order to row away, at that time the patient is, first and foremost, cannot have a meal, want to hurry up to eat some crude fiber vegetables; If the skin is broken mercury thermometer cut, is likely to cause infection, cause skin irritation; And if the mercury into the man's blood, can lead to mercury poisoning. The price is cheaper, up more than ten dollars, but mercury itself is dangerous, so it's best to avoid to acute critically ill patients, the children and the elderly to use. Measurement time is longer, reading more trouble, etc. Mercury thermometers are gradually being phased out. The advantages of the electronic thermometer, clinical thermometer using high-precision sensor and microcomputer technology, electronic thermometers can conveniently, quickly and accurately measure the temperature of the human body. Electronic thermometer shell using Japan imported non-toxic plastic, electronic thermometer easily broken without traditional mercury thermometer, mercury pollution of environment and the difficulty in reading. Electronic thermometer faults: lack of electronic thermometer is value for accuracy affected by factors such as electronic components and the status of the battery, as mercury thermometer.
