Blackbody Calibration Sources

To calibrate infrared pyrometers and thermal imaging systems accurately, it is necessary to have a source of IR radiance that is controlled and predictable. PSC-BBS series of blackbody calibration sources provide a target of known emissivity, temperature and aperture size. These blackbodies can also provide calibration traceability to certified laboratories and national standards.


The Process Sensors BBS1700 Benchtop blackbody calibration source operates in a wide temperature range from 300°C to 1700°C (572°F to 3272°F). This blackbody calibration source provides a large 1-inch aperture with high accuracy and uniformity, long term stability and a fast slew rate.


The BBS1500-38 is a highly stable calibration source which provides automatic calibration. It is ideally used for the calibration of short wavelength pyrometers and thermal imaging cameras between 300 and 1500°C. The large aperture size allows for easy alignment between the blackbody and the device under test.

BBS1050 and BBS1200 Compact Blackbody Sources

The BBS1050 and BBS1200 Compact Blackbody Sources offer high accuracy in up to 1" aperture in a compact form factor. Designed for compact mid to high temperature applications (50 to 1200°C), making them ideal for smaller systems.

BBS1150 High Temperature Calibration Source

The BBS1150 is perfect for mid to high temperature applications. User selectable temperature set points within 200° to 1150°C (BBS1150). Simply adjust the set point on the precision digital PID controller to any temperature within the specified temperature range and the BlackBody should stabilize and begin reading.

BBS120 Series TE Cooled Blackbody Calibration Sources

The PSC-BBS120-TE is well suited for the calibration and verification of non-contact infrared thermometers, thermal imaging cameras, FPA (focal plane arrays), and spectrometers. Optional USB interface with software enables the control of the blackbody via a PC. Temperature ranges begin with a low of -15°C to a max of 120°C.

BBS EX Extended Area Blackbody Calibration Source

The PSC EX series of black body source offer a range of temperatures in a 12" x 12" black body calibration source. Ambient temperature ranges starting from to 230ºC and ending at 500°C.

BBS-EX-TE Blackbody Series

Various Blackbodies with a large uniform extended area emitter plate used for thermal imaging camera calibration and focal point array detectors (FPA). Comes in a variety of emitter sizes and temperature ranges (-5 to 150ºC).


The BBS500-57 is a lightweight Blackbody ideal for the calibration verification of pyrometers and thermal imaging cameras. Used for temperature ranges between 50 to 500°C. Cost-efficient and easy to transport, this Blackbody can quickly be used in many plants, laboratories, and factories.
