Independent Electrical Heater for the Standardization of Radiometric Calorimeters

摘要

The electrical standardization heater is a National Institute of Standards and Technology (NIST) traceable standardization device for calorimeters based on Joulean heating. It may be used on all calorimeters of present and past design. Tests over a wide power range show that the replacement heater is fully equivalent to radiometric heat standards for calorimeter standardization. The replacement heater may confidently be used in lieu of heat standards when circumstances preclude their use. 10 figs., 4 tabs. (ERA citation 14:015636)
