Context

Country: Canada
State/Province: Unknown
Period: 1956+
Canada: One of a set of thermometers used in the Calibration Unit of the Instrument Division of the Meteorological Branch of the Department of Transport of the Government of Canada. Part of a large collection of meteorological instruments acquired from the Meteorological Service of Canada (previously Atmospheric Environment Service) by the CSTM since 1967. MSC is the government agency responsible for collecting and disseminating meteorological data and forecasts in Canada. It was founded in 1871 in Toronto where it is still headquartered. The MSC was originally on the University of Toronto downtown campus but moved to Downsview in 1971 on land owned by UofT. The headquarters houses laboratories, research facilities and calibration and instrument maintenance facilities (now largely contracted out).
Function: An instrument used to measure temperature by means of its effect on a column of mercury in glass, used in a meteorology instrument calibration unit.
Technical: A example of a thermometer made in the German einschlussthermometer style, with the tube attached to a glass scale and the whole enclosed in a glass sheath. The einschlussthermometer was widely used in Continental Europe (Refs. 2-3), but not in Britain or the U.S. This example is marked Eintauchtiefe 110 mm Mittler Fadentemp 25[degrees] C. and is possibly an immersion thermometer for measuring water temperatures. Temperature measuring instrument maker Messgerate-Werk Lauda was founded in 1956 by Dr. Rudolf Wobser and in 1989 was renamed Lauda Dr. R. Wobser GmbH & Co. KG. Lauda is a town on the Tauber River in the German state of Baden-Wurttemberg (Ref. 4).
