To ensure high-precision performance from temperature measurement devices, reliable calibration is required. This can be carried out on site or under laboratory conditions, using primary or reference standard sources.

Primary calibration sources are traceable to National Standards via a certified probe installed in the radiation cavity. Reference sources achieve traceability either by comparison with certified thermometers, or through purchasing a calibration certificate.

AMETEK Land provides primary and reference blackbody sources for all the instruments in their advanced radiation thermometer range. These sources are perfect absorbers and emitters, so calibrations are made with an extremely high level of stability. There are six models in the Landcal range.
