The Cyclops is a hollow black sphere which fits inside our Saturn spherical furnace originally designed to calibrate thermocouples using an equalizing block.
The original equalizing block is removed and in its place the hollow black sphere is substituted enabling the furnace to be used for the calibration of radiation pyrometers.
The emissivity of the material is 0.98. The outer case viewing hole has an aperture of 17mm as standard. An aperture of 50mm is available to special order, giving an apparent emissivity in relation to the wall greater than 0.999. |
