Period

This temperature sensor was apparently in use for 40 years (Ref. 3)

Canada

A thermistor of a type used by the Meteorological Service of Canada to gather temperature data. 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

A meteorological temperature sensing element, possibly for a remote temperature instrument.

Technical

AMSC 400 ohm temperature probe, model M75-001. This is a resistance probe with a military type connector used during the 1960's. While the exact system these were attached to is unknown, the sensors seem to have been used commonly and may be attached to the MSC remote temperature indicator such as 1987.0644. The Meteorological Service of Canada became the Atmospheric Environment Service in 1971 (Ref. 2)
