Calibration of Digital Indicators and Industrial Platinum Resistance Thermometers (-196 °C to 100 °C)
PRT calibrations / Digital Indicators
Industrial platinum resistance thermometers (IPRTs) and digital or analogue indicators with either resistance thermometer or thermocouple probes are widely used as temperature measurement devices in a variety of different applications. NPL provides a service for the calibration of these instruments. This service is UKAS accredited (NPL is a UKAS-accredited calibration laboratory number 0478) and ensures direct traceability to the International Temperature Scale of 1990 (ITS-90).
Calibrations can be carried out between -196 °C and 100 °C in appropriate baths against NPL standard thermometers.
Uncertainties
The calibration uncertainty depends on a number of factors, including the resolution and temperature range for a digital indicator and the range and performance for an IPRT. The uncertainty is therefore assessed for each instrument at the time of calibration, but it can be as low as ±0.005 °C.
Calibration fees
The calibration fees for digital and analogue indicators and industrial platinum resistance thermometers depend on the resolution of the indicator and the required temperature range. They are therefore only available on request. Please contact us with your requirements.
Temperature Measurement and Calibration course
NPL runs a regular ‘Temperature Measurement and Calibration’ course for technicians and technical managers requiring training in the practical aspects of temperature measurement, calibration and traceability. The course includes laboratory sessions covering fixed points, resistance thermometers, thermocouples, radiation thermometers and liquid-in-glass thermometers. These laboratory sessions are supplemented by lectures in calibration techniques, uncertainties, traceability and accreditation.
