Measurement for our planet

As COP26 approaches, discover how NPL plays a key role in enabling climate action through the delivery of accurate, reliable data that supports decision making and enables low carbon innovation.

Temperature and humidity measurements

Air temperature sensors

Range: -40 °C to +100 °C

Traceable calibration of temperature sensors

NPL calibrates thermometers for use in air, both those incorporated within relative humidity instruments and those used purely for air temperature measurement. These calibrations are performed in air, within a temperature-controlled chamber, by comparison against reference thermometers with traceability to national standards.

Calibration in the NPL laboratory
Range: -40 °C to +100 °C
Best uncertainty: ±0.04 °C between -20 °C and +50 °C (at other values: ±0.08 °C)

Calibration above atmospheric pressure in other gases
