Description

Workswell BB FIXED is a black body radiation source with fixed temeperature 35 °C – 60 °C in steps of 5 °C (95 °F – 140 °F in steps of 9 °F) with temperature dispersion  less than 0,3 °C (0.5 °F). The temperature value is fixed from production and cannot be changed by user. Surface  area of Workswell BB FIXED is circular area with 100 mm aperture diameter. There are pyramid shapes on the surface for increasing to increase emissivity and reduce reflektivity. Surface emissivity is 0.95 ± 0.005 for LWIR spectrum. Operating air temperature range is 10 °C to +30 °C.

For calibration of thermal cameras and pyrometers in the laboratory and in the outdoor

Workswell BB FIXED is designed for calibration of thermal cameras and pyrometers Due to its low weight (less than 400g) and low energy (max 24 W, 24 VDC) consumption, it is possible to apply the Workswell BB FIXED black body both 1) in the laboratory and 2) during outdoor measurement, if high demands are placed on accuracy. Workswell BB FIXED could offer long-term time stability better than n ± 0.08% due using precise PID regulation with 16 single thermal elements, measured/checked by certified external PT100 probe, ie. temperature stability of the central area better than ± 0.05 °C. LED signalization for different modes (warming, stabilization, cooling, electronics overheating) is available.
