-Laboratory thermometers
Clinical thermometers:
The thermometers which are used to measure the temperature of the human body. A clinical thermometer consists of a long glass tube having a glass bulb at its one end and the other end is sealed. The glass bulb has mercury inside it. Glass tube has a Celsius scale marked on it. It also has a kink (or constriction) in the glass tube just above the bulb containing mercury. The kink is to prevent back flow of mercury into the thermometer bulb when the thermometer is removed from the mouth of the patient. The kink prevents the mercury level from falling so that we can read the temperature of the patient carefully.
