Thermal Conductivity Resources We Measure Everything

We Measure Everything

Thermtest has started a light hearted measurement program called “We Measure Everything”. Anywhere you see the “λ” symbol, this material has been measured for thermal conductivity or thermal effusivity and presented here. Check back often as we will be measuring some interesting materials!
