principle of six's minimam & maximum thermometer
A Six's maximum and minimum thermometer is designed to measure and record the highest and lowest temperatures reached over a certain period. The two parallel scales on the thermometer show the readings and can be reset manually. This thermometer is commonly used in meteorology and greenhouse monitoring to track temperature fluctuations.
Mercury expands on heating.so at noon when the sun is overhead in the thermometer the Mercury expands and pushes the index down.And then the alcohol which is half filled in the maximum tube rises.then the max.temp is taken.
To reset a mercury barometer after travel, first ensure the barometer has settled to room temperature. Then, carefully check for any air bubbles in the mercury column and gently tap the barometer to release any trapped air. Finally, adjust the mercury column height to match the current atmospheric pressure by turning the adjustment screw if needed.
Demagnetization refers to the process of reducing or eliminating the magnetism in a material. This can be done by subjecting the material to heat, applying an alternating magnetic field, or exposing it to a demagnetizing coil. Demagnetization is commonly used to reset magnetic tapes, hard drives, and other magnetic storage devices.

To reset the index
The advantage is the thermometer records a daily maximum and minimum temperature for reference. The disadvantage is the thermometer must be reset each day.
To read a min max thermometer, look at the two separate scales for the minimum and maximum temperatures. The lowest temperature recorded will be displayed on the minimum scale, while the highest temperature recorded will be shown on the maximum scale. Reset the thermometer to start a new recording period.
These wee steel bars are known as riders, and they mark the travel extent of the Mercury column. They are held in place by a feeble magnet. When the reset button is pushed, it moves the magnet away from the tube, and the riders will settle.
A maximum thermometer typically contains mercury, which expands and contracts with temperature changes, allowing for precise measurements of high temperatures. In contrast, a minimum thermometer usually contains alcohol (often colored for visibility), which contracts more than mercury and can accurately indicate low temperatures. The design of both thermometers allows for the liquids to remain in place at the maximum or minimum temperature recorded until manually reset.
A minimum thermometer is reset by shaking it down firmly and quickly to ensure the indicator moves to the lowest temperature recorded since the last reset. This action allows the indicator to start recording new minimum temperatures accurately.
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.

There is no special name for a maximum-minimum thermometer. It generally consists of two scales one will push a slider up as the temperature increases and the other thermometer pushes a slider down as the temperature goes down. You read it by observing the position of the sliders and then reset it so that the sliders return to the current temperature.
Each side is read at the bottom of the marker that has been pushed upward since the last reading. Don't read the colored fluid where it is at that time. That would only give you the current temperature. The bottom of the maximum marker is at the highest point that it was pushed to at the warmest time since the last reset, and the base of the minimum marker is where the liquid reached at the coldest time. The markers need to be reset at the same time each day with a magnet. Drag the markers back so they are both sitting on top of the silver mercury near the bottom of the tube. Horizontal thermometers are reset by turning them to vertical.
