How do you find the maximum and minimum thermometer?
How to read the thermometer
- The minimum temperature is read on the left hand side – note red indicates below freezing point.
- The maximum temperature is read on the right hand side – black indicates above freezing point.
How does a 6 thermometer work?
Six’s Maximum and Minimum thermometer is a U shaped parallel tube made up of glass. One side registers the maximum temperature and the other side records the minimum temperature. The bend at the bottom of the thermometer contains mercury which moves up or down based on the expansion and contraction of alcohol.
Who invented six maximum and minimum thermometer?
James SixSix’s thermometer / Inventor
When was six maximum and minimum thermometer was discovered?
1780
It was invented by the British scientist James Six, in 1780; the same basic design remains in use. It is also commonly known as a maximum–minimum, minimum–maximum, maxima–minima or minima–maxima thermometer, of which it is the earliest practical design.
Who discovered six maximum and minimum thermometer?
What is maximum and minimum thermometer used for?
Maximum/minimum thermometers are often used to measure a maximum/minimum air temperature for example in a greenhouse. Thus, the transfer liquid should preferably remain substantially liquid up to and above the highest expected temperature.
Who invented the six maximum and minimum temperature thermometer?
scientist James Six
What is the use of Stevenson screen?
They protect the temperature sensors from being influenced by direct or reflected sunlight. Stevenson screens are always painted white to better reflect the sun’s rays. The louvered sides allow outside air to flow around the thermometers.
What is the use of maximum-minimum thermometer?
What is maximum thermometer used for?
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.
What is the use of maximum thermometer?
Why it is called Maximum and minimum thermometer?
Answered on 20th Aug, 2020. Six’s thermometer is a thermometer used to record the maximum-minimum temperatures of a given location within a given time period, for instance, 24 hours. It is used to measure the extremes of the temperature. It is also called a maximum-minimum thermometer.
