What are Maximum and minimum thermometer?
Answers
A maximum–minimum thermometer. The scales are Fahrenheit on the inside of the U and Celsius on the outside. The current temperature is 23 degrees Celsius, the maximum recorded is 25, and the minimum is 15, both read from the base of the small markers in Each arm of the U tube.
Minimum Thermometer.
It is used to measure the minimum temperature within a period (usually daily) and is an alcohol-in-glass thermometer.
maximum thermometer.
A thermometer that records the highest temperature to which it has been exposed (e.g. by allowing a rise of mercury past a restriction in the tube, but preventing the mercury's return on contraction). It is most commonly used to record maximum daily temperatures.
This is the instrument for measuring the maximum and minimum temperature in a day . Here , the two thermometers are connected using a U-shaped glass tube . The Mercury filled in the maximum thermometer expands with the rise in temperature and pushes up the metal indicator . The indicator remains at the position showing the maximum temperature of the day . Thus the maximum temperature can be read at any time during a day . The minimum thermometer has alcohol filled above the indicator . When the temperature falls , the indicator is pushed up as the alcohol contracts . The minimum temperature can be read from the position of the indicator at any time .
