A thermometer with lab thermometer have what difference?

Glass rod can have used as a thermometer thermometer is known to all, have a plenty of use in the laboratory, with the glass thermometer, hit know about laboratory thermometer is relatively less. Laboratory thermometer and the appearance of the thermometer is very similar, are glass cylinder type; Working principle is the same, all is the use of liquid of the principle of heat bilges cold shrink work; And have a temperature measuring head, sometimes the inside of the glass rod are liquid mercury. But the same is not to say we focus, to say today is both the differences of the thermometer. The first difference is that two kinds of table of temperature measurement of liquid in the glass rod is different, the mercury thermometer is primary; Laboratory of liquid in the thermometer is kerosene, under normal circumstances is red kerosene in the home, sometimes will be alcohol or mercury. The second point is the difference between the range and degree value, range of thermometer is fixed, is 35 ~ 42 ℃, because the temperature of the human body generally will not exceed the scope; Laboratory, the range of the thermometer is not sure, generally is - 10 ~ 100 ℃, but there's also, measuring high temperature up to 400 ℃. And the both have the same degree value is not a thermometer is 0. 1 ℃, laboratory thermometer is 1 ℃, this will see thermometer more than laboratory, the high accuracy of the thermometer. The third point is a point on the structure of the two different, clinical thermometer in the temperature measurement with the glass rod part has a mouth, and the laboratory thermometer. This led directly to the fourth and the fifth, is a thermometer can leave the measured object, laboratory thermometer can't; Before and is to use a thermometer to jilt a before use, make mercury returned to the temperature inside the package, laboratory thermometer don't need so trouble, it is good to measure directly. These differences, should be able to let everybody to accurately distinguish the thermometer thermometer and lab, although is a glass rod thermometer, but the difference is very much.
