Process Sensors offers a comprehensive range of blackbody calibration sources designed for accurate calibration of infrared pyrometers, thermal imaging systems, and other radiometric instruments. These sources provide stable, high-emissivity IR radiance with known temperature and aperture specifications, supporting calibration traceable to ITS-90 standards.

The product line includes:

• Compact models (e.g., BBS1050, BBS1200) for mid to high temperature applications (50°C to 1200°C) with up to 1″ aperture
• High-temperature units (e.g., BBS1500-38, BBS1700) with ranges up to 1700°C and large apertures for precise alignment
• Extended area sources (e.g., BBS-EX series) for thermal imaging calibration with emitter plates up to 12″ x 12″
• TE-cooled models for low-temperature calibration down to -30°C
• Portable options like the BBS500-57 for flexible lab and field use

These blackbodies are compatible with FPA detectors, spectroradiometers, heat flux meters, and more.
