Pyrometer black body calibration source SR-2108A

The SR-2108A is a forehead-temperature blackbody cavity designed in accordance with U.S. standards. It achieves an effective emissivity of over 0.999, with a cavity wall thickness of 2 mm, manufactured from pure copper and coated with a non-reflective black paint on the inner surface. The complete blackbody assembly consists of the blackbody cavity and a submerged water tank bayonet mount, and is intended for use when immersed in a constant-temperature water bath. - Range (at 23°C ambient): 15 ℃ to 50 ℃ (59°F to 122°F) - Working Area (Conical): Diameter 92mm (3.6"), Depth 106mm (4.2"), Hole 50mm (2") - Casing Material: Copper - Effective Emissivity: ≥0.999
