Do you know the difference between the lab thermometer and a thermometer?

With regard to the difference between the lab thermometer and clinical thermometer, we can be in two ways, one is the same, while the second is the differences. Principle is the same: both are using liquid made of the nature of the heat bilges cold shrink ( When the temperature rises, the bubble in the liquid, liquid level rise: when the temperature drops and the liquid inside the bubble contraction, drawdown) 。 Are using Celsius temperature. The difference is: ( 1) Range: different experimental, thermometer generally range is - 20C- 110C。 The range of the thermometer is 35 c - 42 c generally in 35 - because the body's temperature range 42 c. （ 2) Dividing the value of different: the experiment with temperature score value of 1 c, and a thermometer degree value is 0. 1C。 （ 3) Within different materials: the experiment with built-in liquid thermometer for kerosene (commonly To facilitate observation, plain dyed red) Normally, within a thermometer liquid mercury. （ 4) Structure: different experimental basic construction is the upper glass bulb thermometer thin tube is uniform. And body above the glass bulb containing mercury thermometer has a do very fine mouth, the mercury thermometer inflation by reducing up to the upper glass tube, when left the body thermometer, mercury cooling contraction, mercury too late return the glass bulb, on reducing the disconnect, still indicate the temperature of human body. So the thermometer readings can leave the human body. （ 5) Usage: the thermometer used cannot leave the reading of the object to be tested, but the thermometer readings can leave the human body. Before using the thermometer is flung down hard a few times with the hand, and other ordinary thermometer is not left before use.
