Captec Enterprise, France

Captec is a leading manufacturer of customized heat flux sensors, radiant flux sensors, solar heat flux sensors and thermal conductivimeter. 

Heat Flux Sensors 
They are designed to measure total heat transfer through conduction, convection, radiation and deliver an output voltage directly proportional to the total heat flux without requiring temperature compensation. 


Radiant Flux Sensors 

The thin foil radiant flux sensor measures the thermal radiation emitted from or absorbed by its sensing area even in the presence of heat transfer through conduction and convection. 

Thermal Conditivimeter 

Designed to measure thermal conductivity without comparison sample, it is an absolute measurement. 

Captec shall be more than happy to customize their flux sensors to your exact needs : size, shape (e.g., circular or rectangular), sensitivity, rigid or flexible, water-proof, operating temperature etc.
