Leading provider of Thermal Conductivity Testing and Thermal
Conductivity Instruments as well as Thermal Resistivity,
Specific Heat Capacity and Thermal Diffusivity.
The Transient Line Source (TLS) Thermal Conductivity Meter is an advanced meter capable of testing soils and rock. The TLS follows ASTM D 5334 and IEEE Standard 442-1981.
TLS can use two different probe types: full-space probes that are fully inserted into the sample and half-space probes that are put on top. Both probe types have a rugged design, cover a wide measuring range and can be used for a great variety of sample materials and sizes. An additional field probe for in-situ testing is available.
