Temperature standards used by Measurement Canada inspectors and authorized service providers are calibrated for use in the field.
Only standards used by Measurement Canada inspectors and authorized service providers are calibrated by Measurement Canada's laboratories. Standards and apparatus must be authorized and registered with Measurement Canada to qualify for this service.
Method
Direct read against reference standards probe in liquid circulating bath providing a uniform temperature distribution of:
- direct-read digital thermometers with one or more probes, and a temperature range within -40 °C to +125 °C
- high accuracy resistance thermometers and thermistors with immersion type probes which use temperature and resistance correlation (e.g. Callendar-Van Dusen or Steinhart-Hart equations). Resistance readout and temperature probes are calibrated as a system over a range within -40 °C to +125 °C
Measurement conditions
- Temperature: 23±5 °C
- Humidity: 10%–80% relative humidity, non-condensing
- Pressure: Ambient pressure
Calibration location
- All devices are calibrated by Measurement Canada's Approval and Calibration Services Laboratory in Ottawa, Ontario.
Fees
- No fees apply for devices used under the application of the Weights and Measures Act.
- See the service fees for the certification of electricity and gas measuring apparatus for all other devices.
