Describe the construction and function of clinical thermometers
Answers
Answer:
Clinical thermometer is a sensitive Fahrenheit scale thermometer. For measuring temperature of human body this thermometer is extensively used. For this reason this thermometer is called clinical thermometer or doctor’s thermometer.
Construction: It consists of a cylindrical bulb B which is filled with mercury. A capillary tube T of uniform and fine bore is attached to the bulb. Just above the bulb at point C the tube is made narrow and bent. Since the temperature of human body varies from 95°F to 110°F, the thermometer is calibrated in this temperature range. Each degree is divided into five small equal divisions. Besides, as the temperature of a healthy man is 98.4°F, so special bold or red mark is made on the surface of the thermometer at 98.4°F.
