MSE PRO™ Transient Plane Heat Source Method Thermal Conductivity Tester

Overview

The MSE PRO™ Transient Plane Heat Source Method Thermal Conductivity Tester utilizes transient planar heat source (TPS) technology to measure the thermal conductivity of a wide range of materials. As a mid-scale thermal analysis method, the transient planar heat source technique significantly enhances measurement accuracy and efficiency, setting a new standard in thermal conductivity testing. It offers a fast, non-destructive, and reliable solution for evaluating thermal conductivity, making it ideal for quality control, material development, and laboratory research. Designed for user-friendly operation, it features a straightforward testing procedure that ensures ease of use without compromising performance.

Working Principle

Transient Planar Heat Source (TPS) technology, developed by Professor Silas Gustafsson of Chalmers University of Technology, is an advanced method for measuring thermal conductivity. It uses a disc-shaped, double-helix flat probe made from a conductive alloy, which functions simultaneously as a heat source and temperature sensor.

The principle is based on the transient temperature response of the probe when a current is applied, generating heat that diffuses through the surrounding material. The rate of heat diffusion—determined by monitoring resistance changes over time—correlates directly with the material’s thermal conductivity. The probe features a thin, double-layer insulating coating to ensure electrical insulation and mechanical stability. During testing, it is sandwiched between two sample sections, allowing precise, non-destructive measurements based on a well-defined mathematical model.

    Key Features

    • Fast & Accurate: Delivers results in just 5–160 seconds.

    • Non-Destructive: Samples remain intact and reusable.

    • Easy Sample Prep: No strict size requirements.

    • Versatile Compatibility: Suitable for solids, powders, liquids, colloids, pastes, and more.

    • Flexible Testing: Features a detachable probe and independent sample holder.

    • User-Friendly Interface: Intuitive LCD touchscreen for simple operation.

    • Instrument reference standard: ISO 22007-2 2008

    Test Objects

    A wide variety of materials can be tested, including metals, ceramics, alloys, minerals, polymers, composites, paper, fabrics, and foam plastics (e.g., flat insulation materials). Other testable objects include mineral wool, cement walls, glass-reinforced composite panels (CRC), cement polystyrene panels, concrete, fiberglass panels, honeycomb paper panels, colloids, liquids, powders, and both granular and paste-like solids.
