Paper-thin, flexible RdF Micro-Foil™ Heat Flux Sensors easily attach to any flat or curved surface and are completely non-invasive.
For precise measurement of heat transfer (loss or gain) through any material surface.
Effective with all methods of heat transfer, including radiation, convection, and conduction.
Linear millivolt output gives the heat transfer rate.
Dual function model measures both heat transfer and surface temperature with embedded thermocouple.

RdF Micro-Foil™ Heat Flux Sensors are individually calibrated at a base temperature of 70°F (21°C). Generally, the sensor is calibrated for low levels by conduction in heat flow series with a traceable standard. The result is a calibration constant for microvolt output per unit of heat transfer rate. Models with heat sinks for high heat flux are calibrated for millivolt output at traceable levels of thermal radiation over the range and a curve is supplied. Calibration curves are typically linear. Each sensor is individually packaged with its calibration data.
