With a temperature range of 100 to 1300°C, the Isotech Model 878 Cyclops blackbody source features a spherical construction with an inner black sphere that sits inside of a spherical furnace. This makes the Model 878 suitable for use as a radiation source for infrared thermometers. The stability of this unit is ±0.1°C and it features an emissivity of greater than 0.999. The display resolution is 0.1°C up to 999.9° and 1.0°C from 1000 to 1300°.
The inner sphere of the Isotech Model 878 Cyclops has a nominal diameter of 230mm and is accessed by an optical sighting tube. The furnace can be supplied in one of two configurations with aperture sizes of either 17mm or 45mm. Furthermore, the Model 878 furnace can be adapted for thermocouple operation by replacing the inner sphere with an equalizing block and using a different control sensor.
