spirit thermometer

Before morning, the spirit thermometers at Dawson registered seventy degrees below zero.

My lab assistant likes spirit thermometers with purple columns.

Seventy-four below zero by spirit thermometer on the sled."

Thermocouples are popular for lower temperatures, as are spirit thermometers that use alcohol instead of mercury.

The limitation is that the range of utility of the spirit thermometer is much less than the mercury thermometer.

Accuracy of a mercury or spirit thermometer is more a function of the column cross-section being appropriate to the marked lengths indicating temperatures.

The Alcohol thermometer or spirit thermometer is an alternative to the mercury-in-glass thermometer, and functions in a similar way.

But Barbicane had furnished himself with a spirit thermometer on Wafferdin's system, which gives the minima of excessively low temperatures.

Forty-eight hours gone, the spirit thermometer had burst at sixty-eight below, and since that time it had grown steadily and bitterly colder.

At eleven o'clock in the morning the spirit thermometer at the N. A. T. & T. Company's store went down to seventy-five below zero.

"If I was you, Daylight, I wouldn't mush to-day," Joe Hines counselled, coming in from consulting the spirit thermometer outside the door.

To atone for this, outer space smote the earth with its cold till the mercury froze and the spirit thermometer remained more than seventy below for a fortnight, when it burst.

In truth, that day at Fort Yukon, the spirit thermometer registered seventy-five degrees below zero, which, since freezing- point is thirty-two above, was equivalent to one hundred and seven degrees of frost.

They had not been so cold as this, he knew, but by the spirit thermometer at Sixty Mile he knew they had been registered at fifty below and at fifty-five.

When the spirit thermometer purchased in Edmonton stood at minus forty-three the two younger men did not relish running the oval, but Luton and Harry missed only when heavy snow was actually falling, which was rare.

Jacques-Barthélemy Micheli du Crest creates a spirit thermometer, making use of two fixed points, 0 for "Temperature of earth" based on a cave at Paris Observatory and 100 for the heat of boiling water.

In 1898 it was especially bitter along the Mackenzie, with the spirit thermometer staying below forty for days at a time, but when the cold was most oppressive Carpenter would say: "When it breaks, we'll have summer in winter!"

Spirit thermometers have higher resolution over their range of utility because the density of the fluid is much less than mercury and the coefficient of expansion of the fluid, that is, change in volume/change in temperature is larger than mercury [I think].

This means that the expansion of the spirit (in spirit thermometers) or the thermocouple (in digital thermometers) will continue for so long as energy can be transferred to the thermometer - and energy will continue to be transferred until the substance being measured and the thermometer have the same average particle velocity.
