THB Transient Hot Bridge - thermal conductivity measurements

THB - Thermal Conductivity Meter - Transient Hot Bridge

The Linseis Transient Hot Bridge technique enables thermal con-ductivity, thermal diffusivity and specific heat measurements on various sample geometries and materials. This Linseis measuring instrument provides the three material properties simultaneously after just a few minutes time – regardless of whether you have used the patented sensor in a solid matter (incl. bulk material, gels, pastes) or in a liquid.The preparation of solid samples is pretty simple: One pla-ne surface of two sample halves is sufficient for the sensor. Reference or calibration measurements are a thing of the past. As a matter of course, the THB measures absolute values, with an uncertainty which is not behind that of con-ventional plate or our laser flash devices.

Different sensors, easily to be exchanged, are available for laboratory and field use. The THB measures fully automatically. Its software control optimizes the measurement process independently, aiming at a short duration and a minimum uncertainty. In addition, it continuously monitors a possible temperature drift of the sample. Due to the short measurement times, serial mea-surements can be performed at a forced sequence and with a high sample output. In addition to the measurement values, the Software calculates and displays the associated measurement uncertainties in accordance with the international ISO standard.
