Thermal Conductivity Instruments

LFA / THB / TIM-Tester / HFM and many more

The most common way to measure thermal diffusifity will be the well known Laser flash method (LFA). Here a sample is pulsed with a Laser and an IR detector on the opposite detects the temperature rise of the sample, what leads to the thermal diffusifity. If the density and specific heat capacity are known, the thermal conductivity can be calculated.

The TIM-Tester is our new instrument for the analysis of thermal interface materials like thermal fluids, thermal pastes (greases), phase change materials (PCM), solders or resilient thermal conductors. The TIM-Tester measures the thermal impedance of sample materials and identifies an apparent thermal conductivity.

The Transient Hot Bridge method (THB) is made for solids, liquids and pastes and gives the thermal conductivity as direct result of the measurement with high accuracy within a few minutes. It is suitable for isolating materials as well as conducters like metals.

The heat flow meter (HFM) is a special instrument for quality control in factories. It needs bigger sample sizes but can measure the thermal conductivity with highest accuracy, using an exact controlled temperature gradient.

For thin film samples and micro samples, known from the computational industries, there are also the new thin film laser flash (TF-LFA) and thin film analyzer (TFA), that can measure the desired thermal conductivity and diffusivity with highest precision as well.

The LINSEIS Thermal Conductivity instruments operate in agreement with national and international standards such as ASTM E1461, DIN EN 821, BS EN 1159-2, ASTM C714, ASTM C518, ISO 8301, DIN EN 12667 EN 12 and ASTM D5470.
