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.

Advantages at a glance:

Unsurpassed measurement accuracy for determining thermal conductivity
One-button solution:
- Automated measurement mode
- No specialist personnel required to operate the instrument
- No erroneous measurements due to incorrect measurement parameter input
Thermal conductivity AND thermal diffusivity
- Measurement of thermal diffusivity with very low measurement uncertainties
- Calorimeter function: Calculation of specific heat capacity
Measurements within seconds
Non-destructive measurements with half-shell sensor
Compact dimensions

Complies to the following Norms: ASTM D 5930-01, DIN ISO 2200-2, ASTM D 5334.
