BB39
is designed for purpose of calibration industrial and laboratory pyrometers.
It has 30 mm opening.
It has tube-shape radiator with cylindrical cavity. The radiator can be easily replaced for spare one (spare radiators are included in the delivery set).
BB39 has no output glass window. Argon, flowing out from the blackbody opening, is usually used to prevent oxidizing of graphite. You can also close the opening with quartz window and operate BB39 with vacuum or inert gas inside the chamber.
BB39 has two modifications: BB39/2000 and BB39/2500 with different maximum working temperature – 2000?C and 2500 ?C respectively.
