Optical pyrometer

This PYRO Optical pyrometer features a circular direct reading scale on the instrument which allows one to compare the intensity of light radiated from a target at a wavelength of 655 nm to the known brightness of a calibrated lamp. Both radiators are assumed to be black bodies. The pyrometer allows the temperature of a incandescent body, such as a light bulb filament, to be found from a distance.

 

Temperature readings are accurate to within to ±.0.5%. The minimum target size and range are 2 mm and 10 cm respectively. Supplementary magnification lenses for smaller targets at shorter distances are available..
