MEDTHERM 64 Series Gardon gage offer dependable direct measurement of heat transfer rates in a variety of applications due to careful design, rugged quality construction and versatile mounting configurations. Each transducer will provide a self-generated 10-millivolts (nominal) output at the design Gardon gage. Continuous readings from zero to 150% design heat flux are made with infinite resolution. The linear transducer output is directly proportional to the net heat transfer rate absorbed by the sensor.
64 Series transducers have for almost forty years met thousands of application challenges in ground and flight aerospace testing, fire testing, flammability heat flux standards, heat transfer research, materials development, and furnace development.
CALIBRATION
Each gardon gage is provided with a certified comparison calibration per written procedures to ANSI/NCSL Z540-1, ISO 10012-1, and ISO/IEC 17025. Calibrations are traceable through temperature standards and electrical standards to the National Institute of Standards and Technology (NIST). Calibrations are radiant calibrations, referenced both to blackbody simulators as source standards and to a set of MEDTHERM Kendall Absolute
Cavity (ECR) Radiometers as detector standards. Special calibrations are also available.
