A comprehensive range of six LANDCAL blackbody calibration sources provides high precision calibration of radiation thermometers within the temperature range -10 to 1600°C/15 to 2900°F, both on-site and under laboratory conditions.
The sources are divided into two main groups, classified as being either primary or reference standard. The primary and reference standard sources are further divided into Portable,
Transportable or Bench mounted groups. Primary Standard Sources The calibration of a primary source is traceable directly to National Standards via a certified probe installed in the radiation cavity. Reference Standard Sources
Traceability to National Standards can be achieved either by using optional certified radiation thermometers for calibration by the comparison method, or by purchasing a certified source.
P1200B
LANDCAL P1200B is a bench mounted, primary standard, variable temperature source designed for testing and precise calibration of most industrial radiation thermometers, thermographic equipment and thermocouples.
P1600B2
LANDCAL P1600B2 is a bench mounted, primary standard, variable temperature source designed for testing and precise calibration of most high temperature industrial radiation thermometers, thermographic equipment and thermocouples.
P550P
LANDCAL P550P is a portable, variable temperature, blackbody radiation source. It is a primary standard designed for high precision calibration of low temperature radiation thermometers.
P80P
LANDCAL P80P is a portable, variable temperature, blackbody radiation source. It is a primary standard designed for high precision calibration of low temperature radiation thermometers with sub-zero measurement capability.
LANDCAL R1200P
LANDCAL R1200P is a high stability portable, blackbody reference standard source. R1200P can be used for both on-site or laboratory calibration of a range of short wavelength thermometers, such as System 4 and Fibroptic radiation thermometers.
LANDCAL R1500T
LANDCAL R1500T is a high temperature, transportable blackbody radiation source designed for calibration of a range of thermometers such as System 4 and Fibroptic thermometers. R1500T is a reference standard source giving a resolution of ±1 °C/2 °F.
