State similarities and differences between the laboratory thermometer and the clinical thermometer.

AcademicPhysicsNCERTClass 7

A clinical thermometer is a thermometer used to measure the temperature of human beings. It can be tilted while taking the reading. A Laboratory thermometer is used to measure temperature changes with a high range of precision. It has a long stem with a silver bulb at the end. It can be partially or fully submerged in a liquid. It actually used to measure the freezing point, boiling point, etc. of liquids.

Similarities between a clinical thermometer and a laboratory thermometer:

  • Both the thermometers are made of glass and consist of a long narrow glass tube.
  • There is a bulb at one end of both of the thermometers.
  • There is mercury in the bulbs of both thermometers.
  • In both the thermometers, the temperature is measured on a celsius scale.

Difference between clinical thermometer and laboratory thermometer

Clinical thermometer 
  Laboratory thermometer
The range of a clinical thermometer is from 35 degrees C to 42 degrees C.
The range of laboratory is from -10 degrees C to 110 degrees C.
A clinical thermometer has a kink, which prevents the immediate backflow of mercury.
A laboratory thermometer doesn't have a kink
Is Used to measure human body temperature.
It is used to measure temperatures other than the human body temperature in the laboratory.
