Period

ca. 1940's and 1950's

Canada

A type of thermometer used by the Canadian Meteorological Service at its observing stations, specifically at Aishihik or Snag, YT. Both stations were established as airstrips for the Americans in 1942, taken over by the Canadian gov't after WWII, and used until the late 1960's (see donor's letter in supp. info.) This could be the thermometer that measured the lowest temperature ever recorded in Canada (81.6 deg f) at Snag, Yukon in February 1947.

Function

An instrument that measures the lowest or minimum temperature by means of a conical glass index which remains fixed in a column of alcohol at the lowest point to which the liquid drops.

Technical

A double tube or sheathed minimum thermometer with a cylindrical bulb, of the kind used by the Canadian Meteorological Service before 1951, after which sheathless thermometers were used. The double tube served to protect the scale from weathering.
