Abstract:
The table of corrected optical pyrometer readings enables optical pyrometer users to convert observed temperature immediately to the true temperature, if the effective emissivity of the material being observed is known. The table gives observed temperatures from 1,000 to 3,000 K in increments of 5 degrees, from 3,000 to 5,000 K in increments of 10 degrees, from 5,000 to 10,000 K in increments of 50 degrees, and from 10,000 to 39,900 K in increments of 100 degrees. For these, true temperatures are tabulated for 49 emissivities ranging from 0.02 to 0.98 in increments of 0.02. These calculations were made on a 650 electronic computer using Plancks law, and the value c sub 2 1,438 cm deg for the radiation constant.
