Heitronics ME30 Blackbody Calibration Source
Temperatures from -20oC to +350oC
According to the latest development in technology a Blackbody Calibration Source has to be used to calibrate infrared radiation thermometers and thermal imaging systems with temperature ranges within –20 °C to 350°C.
An ideal blackbody sends out radiation - in a defined wavelength region - which only depends on its temperature. Its emissivity is 1 (Planck's law of radiation). A surface which comes very close to this perfect radiator is achieved by the aperture of a cavity whose inner surface is blackened and at a uniform temperature.
When the opening is small with regard to the dimensions of the cavity, blackbody behavior is approximated and the emissivity approaches 1. This condition is achieved by a cylinder (tube with a bottom) when the ratio length to diameter is high. Therefore the opening of the cylinder is excellently suited as a calibration source for infrared radiation thermometers and thermal imaging systems.
The universal blackbody ME30 meets all requirements for adjusting and calibration of radiation thermometers according to VDI/VDE-guideline 3511, Temperature measurement in industry, Part 4 Radiation thermometry and Part 4.4 Calibration of radiation thermometers.
