Providing the same high precision as our advanced temperature monitoring products, a comprehensive range of six calibration sources lets you calibrate radiation thermometers across a temperature range of -10 °C to 1600 °C (15 °F to 2900 °F).

As Landcal blackbody sources are perfect absorbers and emitters, calibrations are made with an extremely high level of stability; all calibrations are traceable to National Standards, delivering confidence to your measurements.

All calibration requirements are covered, with low, medium and high range temperature versions available in bench-mounted, portable and transportable versions.


Landcal primary sources use a certified probe installed in the radiation cavity to achieve traceability to National Standards. Reference sources can achieve traceability by comparison to a certified thermometer, or by purchasing the source with a calibration certificate.


Between them, the models in the Landcal range cover a temperature range from sub-zero Celsius levels (-10 °C, or 15 °F) to very high temperatures (1600 °C, or 2900 °F), ensuring a suitable match to your thermometer.


All of AMETEK Land’s radiation thermometers are covered by the Landcal range. Whatever your temperature measurement technology, there’s a calibration source that fits your system, with portable, transportable and bench-mounted versions available.

AMETEK Land’s Landcal range is available in six different models - Find the model to match your thermometer below.
