Using the TPS-EFF Meter and optional Compression Stand (TPS-EFF-CS), a memory foam sample was measured at a force 1 lb and 2 lbs.
SAMPLE: Memory Foam | |
---|---|
Compression Force: | 1 lb |
Test time (2 seconds): | 73 W√s/m2K |
When the foam is compressed, there is an increase in density, which increases the thermal effusivity.

Thermal Effusivity Meter (TPS-EFF) is an advanced measurement meter for direct determination of thermal effusivity of textiles, fabrics, and solids, in accordance with ASTM D7984-16. TPS-EFF uses a single-sided TPS sensor along with 2 and 10 second test times to fully understand measurement of comfort with touch time.
