Question

Identify the type of thermometer shown below.

• A. Laboratory Thermometer
• B. Clinical Thermometer
• C. Digital thermometer
• D. Can be laboratory or clinical thermometer

Answer 1

The correct option is B Clinical Thermometer

A kink (also called as constriction) is used in a clinical thermometer to prevent falling of mercury by its own. If it is not used then, the moment you draw thermometer out from your mouth, mercury level will come down and you will not be able to see the exact temperature.

Laboratory thermometers are high precision thermometers which have a different range than clinical thermometer and do not have a kink.
Digital thermometers also do not have a kink.
