Difference between the clinical and the laboratory thermometer?
Answers
A clinical thermometer has a temperature range of only 35ºC to 42°C.
Laboratory thermometer: is used to measure the temperature of all things, except the human body. It is a complex device. A laboratory thermometer has a temperature range of -10°C to 110°C
The clinical thermometer is a specially designed and calibrated thermometer to measure our body temperature search thermometer is known as clinical or doctors thermometer. The clinical thermometer differ from an ordinary laboratory thermometer in two respects :
(i) It is calibrated from 35°C – 42°C only. This is so because this is the range over which the temperature of the normal human body can vary.
(ii) It has a slightly bend or king in Its capillary tube. This king is given the name 'Constriction'.
The Constriction ensure that the Mercury thread does not fall back by itself after this thermometer has been used to measure the temperature of a person which can read the temperature of a person and therefore can be taken conventienly. This would not be the case if any ordinary laboratory thermometer was used for this purpose. Whereas The laboratory thermometer is used for measuring the temperature that the substance is in which degree , it is calibrated from -10° – 110°.
