Thermal Conductivity & Diffusivity

Transient Hot Bridge THB


The LINSEIS Transient Hot Bridge THB series is able to measure automatically the thermal conductivity and thermal diffusivity and specific heat measurements on different types of sample geometries and materials. This instrument can give the three material properties mentioned simultaneously in a matter of few minutes, regardless of which sensor you used and the state of matter used (solid, gel or pastes).

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.

The main advantages of THB instruments are:
• Sample preparation of the solid to be measured is simple. Calibration of the instrument is simple and quick.
• THB instrument measures absolute value of thermal conductivity with high accuracy.
• Rapid measurement within seconds.
• Non-destructive measurement with half-shell sensor.
• Complies with standards: ASTM D 5930-01, DIN ISO 2200-2, ASTM D 5334.

Three (3) models of THB instruments are available: Basic, Advance and Ultimate
