It consists of a U-shaped glass tube with two separate temperature scales set along each arm of the U. One of these is for recording themaximum temperature encountered and the other for the minimum temperature. The arms of the U-shaped tube terminate in sealed glass bulbs. The bulb at the top of the minimum reading scale arm is full of alcohol, the other contains a vacuum (or low pressure alcohol vapour). [1]
[2]
In the bend of the U is a section of Mercury. This is pushed around the tube by the thermal expansion and contraction of the alcohol in the first bulb as it responds to the external temperature. The near vacuum in the other bulb allows free movement of the alcohol and mercury. It is the alcohol which measures the temperature; the mercury indicates the temperature reading on both scales.
The thermometer shows a reading at the top of the mercury section on both the maximum and minimum scales; this shows the current temperature
The maximum and minimum readings are recorded by two small steel markers which are sprung into the capillary tube so that they cannot easily slide unless a small force is applied to them.
Before a maximum or minimum reading can be taken, both markers must be returned to the top of the mercury, usually by hand using a small magnet to slide them along the tube. Any change in temperature after that time will push one of the markers along with it.
If the temperature is rising, then the maximum scale marker will be pushed. If it falls after the reset, then the moving mercury will push the minimum scale marker. Often both things happen one after another as the temperature changes, say through a twenty-four-hour period (see diurnal temperature variation). The markers thus record the furthest point reached by the mercury in each arm of the tube. They record the extremes of temperature experienced by the device since it was last reset. The thermometer is usually reset every day, but if left for longer the readings would show the highest and lowest temperatures encountered since the instrument was last reset.
To take a reading, the positions of the ends of the markers nearest to the mercury are examined. Their positions on the maximum and minimum scales show the highest and lowest temperatures encountered over the period of measurement
A combination maximum thermometer and minimum thermometer; the tube is shaped in the form of a U with a bulb at either end; one bulb is filled with creosote which expands or contracts with temperature variation, forcing before it a short column of mercury having iron indexes at either end; the indexes remain at the extreme positions reached by the mercury column, thus indicating the maximum and minimum temperatures; the indexes can be reset with the aid of a magnet.
hope this satisfies you..........
A Six's Thermometer is used to measure the minimum and the maximum temperature of a day. that's why it is also called maximum-minimum thermometer.
it is a device of great use at meteorological centers.

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.
the indicator (index) stays at the position to which it is pushed by the mercury or alcohol in the glass tube of the thermometer,even when the mercury has moved down
my phone number is this and u may call me and ask me this answer and i was a professor of geography i am nw=ew in India...Mr.Xenon-9674218773
i dont know
JAMES SIX invented the Maximum and Minimum thermometer in 1782.
Depends on the thermometer. If it's a weather thermometer, then you use it outside. If it's a body temperature thermometer, then you use it in the mouth or behind.
the thermometer is used to measure the temperatures.
platinum resistance thermometer
You can use a thermometer or a weather app on your smartphone to tell the temperature outside.
six's maximum and minimum thermometer is used to measure the temperature
Six's thermometer is a thermometer which can measure the maximum and minimum temperaturesreached over a period of time, usually during a day.
the use of the six's maximum and minimum thermometer is the find the highest and the lowest temperature for a day. At the meterological station this instrument is usually kept in a stevenson screen...lolz

Six's thermometer is a thermometer which can measure the maximum and minimum temperaturesreached over a period of time, usually during a day.
A Six's thermometer is a thermometer invented by James Six, which is capable of measuring the maximum and minimum temperatures during a given time. This makes it very useful for measuring extreme temperatures.
use thermometer in fever.
JAMES SIX invented the Maximum and Minimum thermometer in 1782.
What kind of thermometer you use to measure the body temperature
Depends on the thermometer. If it's a weather thermometer, then you use it outside. If it's a body temperature thermometer, then you use it in the mouth or behind.
Absolutely, the thermometer is independent of any other measuring device, therefore the actual temperature is dependent on the reading that is taken off the thermometer.
James Six invented it in the year 1782
