Trident
“When all you have is a hammer, everything looks like a nail.” The adage rings true in thermal conductivity characterization. It’s better to have options. Trident unleashes the power of three different transient methods with the ultimate toolbox for thermal conductivity measurement. MTPS, TPS and TLS all in one modular package. Choose the right tool for your samples. Choice is good.
Applications
The Trident platform allows for thermal conductivity testing of a wide range of solids, liquids, powders and pastes.
