The BBS1500-40 can generate calibration certificates for PSC infrared sensors under test using new SensorCal3 software. It combines the features of a precisely controlled temperature source with the calibration and adjustment tasks. The large-aperture blackbody calibration source, which offers a temperature range of 482-2732°F (250-1500°C), communicates with connected pyrometers and transmits and receives measurement data for manual or fully automatic tasks. A PC is connected to the BBS1500-40 and a pyrometer undergoing calibration. The SensorCal3 software can then generate a calibration certificate.
