THB Basic
Unsurpassed measurement accuracy
THB sensors
Reference material
Furnaces and other accessories
This measuring instrument simultaneously delivers the three material properties thermal conductivity, thermal diffusivity and specific heat after just a few minutes, regardless of whether you have placed the corresponding sensors in bulk solids, gels, pastes or plates or immersed them in liquids.
Sample preparation of solids is as simple as it is straightforward. One plane contact surface of each of two sample halves is sufficient for the sensor. Calibration is very simple and does not need to be performed before each measurement.
The THB measures absolute values with an accuracy that does not lag behind conventional plate or LaserFlash devices.
Complies to the following Norms: ASTM D 5930-01, DIN ISO 2200-2, ASTM D 5334.

Applications
Application: THB Basic/Advance – Phase change material – Thermal conductivity
The thermal conductivity of Sample A slightly increases with heating up to 0 °C, whereas Sample B shows slightly decreasing values. Both samples change from the solid to the liquid state in the temperature range from 0 °C to 10 °C which can also be clearly seen in the thermal conductivity drop. With increasing temperature, the thermal conductivity of both samples increases slightly. In general, Sample B shows higher thermal conductivities compared to Sample A.
Application: THB Advance – Aluminium Alloy – Thermal conductivity
The thermal conductivity of an aluminium alloy was investigated from room temperature to 100 °C using the THB. For the measurement the QSS sensor was placed between two sample pieces and pressed together for an improved thermal contact. The configuration was placed in a furnace and the temperature steps were room temperature, 50 °C and 100 °C. At each step the measurement was repeated three times and the results were averaged. In the diagram one can see that the thermal conductivity is slightly decreasing with temperature. The error bars show an uncertainty of 2 %.
