The device which is used to calculate temperature is called Thermometer. What is clinical thermometer? The device which is used to calculate the temperature of our body is called Clinical Thermometer. Structure of thermometer - A long narrow tube with a same thickness throughout the length. On one side of this tube there is a bulb which contains mercury. Also, for reading the temperature there is a scale on the thermometer. The normal temperature of our body is 37 °C. However it can vary between 35° C to 42 °C therefore the clinical thermometer has reading from 35 °C to 42 °C. Units of temperature - 1) Degree Celsius(°C), 2) Kelvin, 3) Fahrenheit(°F). How to use clinical thermometer- 1) Wash with antiseptic solution. 2) Give a jerk to it so the mercury can fall down to the minimum temperature. 3) Place the bulb of thermometer under your tongue for one minute. 4) After one minute take out the thermometer and find out the reading which is shown by the mercury.
