Ivenskii UDC 536.521.2.089.6 In certain areas of industry (cement, tires, food, paper, the chemical industry when manufacturing film materials, etc.) it is necessary to measure temperatures below 600~ using total-radiation pyrometers. In the USSR these pyrometers are not mass produced, and the in- formation is only available on individual developments (see, for example, [i]). The produc- tion of low-temperature total-radiation pyrometers is only possible when reliable methods of measurement, calibration, and checking are available. The use of calibration and checking methods for technical pyrometers based on compari- sons with the readings of similar standard instruments [2] using specially developed equip- ment employing nonblack radiators has become widely used. Thus, in the equipment described in [3, 4] cinema projection lamps with tungsten helical filaments were used as the radiators, and in the apparatus described in [5] a temperature lamp with a tungsten heater in the form of a tape was employed. These equipments were developed for checking acute-angle telescopes with a sighting index of 1/16 or less, measuring temperature higher than 600~ However, these equipments are unsuitable for checking low-temperature pyrometers which, as a rule, have a sighting index of greater than 1/16
