Applications using the TPS-EFF (Transient Plane Source – EFFusivity)

The TPS-EFF (Transient Plane Source-EFFusivity) is a portable meter for direct determination of thermal effusivity of textiles, fabrics and other low effusivity materials, in accordance with ASTM D7984-16. With a single measurement of 2 or 10 seconds in duration, materials can be accurately measured for thermal effusivity.

 Thermal Conductivity Applications Solvents

Fabric and Memory Foam
