Period

Canada

A meteorological calibration instrument designed and made by the Meteorological Service 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 in a meteorological instrument laboratory to calibrate thermometers.

Technical

An example of an apparatus used in a laboratory for the calibration of meteorological thermometers. The end of a thermometer was submersed in the bath section of the apparatus at a controlled temperature and the thermometer was verified against a standard thermometer. The comparisons were done at specified temperatures so the calibration curve could be seen. The curve is not just affected by the zero or 100 C point but also by the consistency of the tube diameter along the length (R.C. Brooks, Nov. 2006).
