What is maximum-minimum thermometer reading?

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.

How does a min/max thermometer work?

This type of thermometer measures both the highest (maximum) and lowest (minimum) temperature over a period of time, usually one day (24 hours). Figure 2.1 shows that a maximum-minimum thermometer is U- shaped. The mercury in the tube pushes the markers as temperatures go up or down.

What is maximum-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.

What’s the difference between maximum and minimum thermometer?

maximum and minimum thermometer – thermometer that records the highest and lowest temperatures reached during a period of time. thermometer – measuring instrument for measuring temperature.

What was the purpose of the six’s thermometer?

Six’s thermometer is a registering thermometer which can record the maximum and minimum temperatures reached over a period of time, for example 24 hours. It is used to record the extremes of temperature at a location, for instance in meteorology and horticulture. It was invented by a British scientist James Six,…

When did Daniel Gabriel Fahrenheit invent the thermometer?

In 1714, Dutch scientist and inventor Daniel Gabriel Fahrenheit invented the first reliable thermometer, using mercury instead of alcohol and water mixtures. In 1724, he proposed a temperature scale which now (slightly adjusted) bears his name.

Which is the upper limit for an alcohol thermometer?

Alcohol thermometer. The range of usefulness of the thermometer is set by the boiling point of the liquid used. In the case of the ethanol-filled thermometer, the upper limit for measurement is 78 °C (172.4 °F), which makes it useful for measuring daytime, nighttime and body temperatures, although not for anything much hotter than these.
