Fast thermal conductivity meter TK04 TK04 with half-space probe and reference standard TK04 is designed for fast and high precision thermal conductivity testing where steady state methods are too time-consuming and conventional transient methods do not meet the accuracy requirements. We have developed an entirely new algorithm for evaluating thermal conductivity measurements using the transient line source method (needle probe method). The accuracy achieved by the new technique is very high (± 2%). Moreover, typical disturbing effects that could affect the reliability of thermal conductivity tests can be made visible to the user.

TK04 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.

Unattended operation controlled by user-friendly software Screenshots TK04 measuring program The instrument can be controlled using any computer or notebook running MS Windows. Measurements are organized in measuring series consisting of an arbitrary number of single measurements (up to 99). After choosing the desired measuring and evaluation parameters, TK04 is working completely unattended without requiring any user interaction. The thermal state of the sample is continuously monitored before and between single measurements. If necessary, a temperature drift (usually caused by instable ambient temperature) is corrected by the measuring software. Using default settings, a single measurement takes 80 seconds, while a typical measuring series consisting of 5 single measurements takes approx. 15 to 30 minutes. Prices include a multi-user license for the comprehensive software package (measuring, evaluation, graphics, quality analysis) comprising an unlimited support period.

Application range Various sample materials TK04 is designed for testing solids, powder, fragments, viscous liquids, and for in-situ tests in the measuring range of 0.1 to 10 W/mK. All probes can be used for wet materials. Samples can be of any size and shape as long they meet the minimum size requirements (see sample preparation notes).
