Explain the mode of Operation of the Six’s Thermometer

Explain the mode of Operation of the Six’s Thermometer

When temperature rises, the alcohol in bulb R expands and pushes the mercury up the right limb of the u- tube. The mercury pushes index Y upwards. The lower end of this index indicates the maximum temperature reached during the specified period.

When temperature falls, the alcohol in bulb R contracts and mercury is pulled back, rising up in the left limb. The index X is therefore pushed upwards. During contraction of alcohol, the index Y is left behind in the alcohol by the falling mercury. The minimum temperature is read from the lower end of index X.

To reset the thermometer, a magnet is used to return the steel indices to the mercury surfaces.
