These non-contact temperature calibration services provide access to the International Temperature Scale of 1990 (ITS-90) as realized by NIST for the temperature range from 15 °C to 4200 °C. NIST disseminates the radiance temperature scale by issuing tungsten strip lamp standards of radiance temperature and by calibrating customer supplied pyrometers, radiation thermometers, and blackbody sources. back to top | back to index of thermodynamic quantities Disappearing Filament Optical Pyrometers (35010C-35040C) Customer supplied pyrometers are calibrated from 800 °C to 2700 °C by comparison to a high temperature blackbody. For temperatures above 2700 °C, measurements at lower temperatures are used to extrapolate the temperature measurements to 4200 °C. back to top | back to index of thermodynamic quantities Tungsten Strip Lamps (35050C-35061C) Tungsten strip lamps are supplied by NIST as standards of radiance temperature. The lamps are calibrated at 655.48 nm from 800 °C to 2300 °C by comparison to a reference strip lamp. back to top | back to index of thermodynamic quantities Radiation Thermometers (35070S-35084C) Customer supplied radiation thermometers are calibrated from 15 °C to 2700 °C using various blackbodies. For the temperature range from 15 °C to 900 °C, NIST calibrates radiation thermometers with central wavelengths between 0.9 µm and 5 µm and between 8 µm to 14 µm by comparison to the blackbodies in the following table. | Blackbody | Temperature Range | Diameter of Cavity Aperture | Emissivity | | Water-bath | 15 °C to 70 °C | 10.8 cm | 0.9997(3) | | Oil-bath | 70 °C to 170 °C | 10.8 cm | 0.9997(3) | | Cesium heat-pipe | 400 °C to 700 °C | 2.2 cm | To be determined | | Sodium heat-pipe | 700 °C to 900 °C | 2.2 cm | 0.99992(3) | For temperatures from 800 °C to 2700 °C, radiation thermometers with central wavelengths of 650 nm, 900 nm, and 1000 nm are calibrated by comparison to a high temperature blackbody.
