Radiometer, Daedalon®

Calibrated in Watts/meter2, the Radiometer will measure the energy of direct sunlight or the warm spot left by a human hand pressed on a wooden desktop. The thermopile detector consists of a series of tiny thermocouples wired in series. The thermopile mounts in a substantial aluminum housing to maintain temperature stability. An integral shutter mounted in the housing cuts off the incoming radiation when adjusting the zero offset of the amplifier. The detector has a flat spectral response from 0.3 μm in the ultraviolet to 15 μm in the infrared. The detector area of about 2 mm2 can measure the energy in a laser beam. For broad sources of radiation, the instrument is sensitive through a 60° cone angle. Broad spectral range Specifications: Detector: 28 junction thermopile Spectral Range: 0.3 to 15 μm Sensitivity: 1000 to 1 W/m2 in 4 ranges Controls: range switch, zero adjust, shutter h x w x d: 12 x 9.5 x 22.5 cm (4.7 x 3.7 x 8.7 in)
