Water-cooled Wheel

2 models each with 6 different diameters

To calibrate or verify the field of view of pyrometers, radiation measurement devices or thermal imagers, apertures of defined diameters are needed in the majority of cases.

With the water-cooled wheel assembly 2 models each with 6 different diameters from 2.54 mm to 25.4 mm or 2 to 50 mm are available, which can be easily attached to calibration sources. Different diameters are selectable by rotating the aperture.

The wheel assembly is cooled by water or dry air to reduce the influence of the background temperature.
