Thermal Conductivity Instruments

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

Measuring Thermal Diffusivity:

The Laser Flash Method (LFA) is the widely adopted technique for determining thermal diffusivity. In LFA, a laser pulse is directed at a sample, while an infrared detector on the opposite end registers the resulting temperature increase in the sample, yielding the thermal diffusivity. When coupled with knowledge of density and specific heat capacity, this method enables the calculation of thermal conductivity.

Introducing the TIM-Tester:

Our innovative TIM-Tester is designed for the analysis of thermal interface materials, encompassing thermal fluids, thermal pastes (greases), phase change materials (PCM), solders, and resilient thermal conductors. The TIM-Tester quantifies the thermal impedance of sample materials, providing insights into their apparent thermal conductivity.

LFA Applications:

The Laser Flash Analysis (LFA) process finds valuable applications in diverse fields. It’s essential for assessing materials like ceramics used in applications such as automobile brake systems and rocket engines. Additionally, it’s frequently used in the chemical industry to determine the conductivity of substances like silicone oils and sodium nitrate, which serve as electrical insulators and phase change materials for thermal energy storage and release.

Heat Flow Meter (HFM):

The Heat Flow Meter (HFM) is a specialized instrument tailored for quality control in manufacturing settings. Although it requires larger sample sizes, it delivers the highest level of accuracy in measuring thermal conductivity by precisely controlling temperature gradients.

Thin Film Laser Flash (TF-LFA) and Thin Film Analyzer (TFA):

For thin film samples and micro-sized materials prominent in computational industries, the Thin Film Laser Flash (TF-LFA) and Thin Film Analyzer (TFA) offer exceptional precision in measuring thermal conductivity and diffusivity.

Transient Hot Bridge Method (THB):

THB is designed for evaluating thermal conductivity in solids, liquids, and pastes. It provides highly accurate results within minutes and is suitable for both insulating materials and conductors, including metals.
