Thermal conductivity tester TCT 716 Lambda

The TCT 716 Lambda offers the capability of analyzing specimens with optimum dimensions: smaller than conventional HFM and larger than LFA. This enables investigations on homogeneous and inhomogeneous materials with Thermal Conductivity Thermal conductivity (λ with the unit W/(m•K)) describes the transport of energy – in the form of heat – through a body of mass as the result of a temperature gradient (see fig. 1). According to the second law of thermodynamics, heat always flows in the direction of the lower temperature. thermal conductivity values ranging from low to medium, for example polymers, composites, glass, ceramics, some metals, etc. The robust design of the TCT 716 Lambda thermal conductivity tester offers easy, uncomplicated handling of the software and hardware. The guarded heat flow meter (GHFM) is fully software-controlled, including mean temperature and applied force. The software also allows for an unlimited number of steps in test cycles for best performance This GHFM has a left and right test stack; which enables tests on a single specimen or simultaneous tests on two specimens. Each stack is independent of the other in terms of clamping force and specimen thickness. Both stacks can be operated across the entire temperature range from -10°C to 300°C. This arrangement not only increases sample throughput, but also allows for more data to be collected in less time. The system provides precise temperature control with a resolution of 0.1°C. It is equipped with multiple high-resolution detectors (RTD), which allow for accurate measurement of the thermal gradient across stack and specimen thickness.
