Transient Plane Source Technology (TPS) is a novel method for measuring thermal conductivity. Developed by Professor Silas Gustafsson of Chalmers University of Technology in Sweden, it builds upon the hot-wire method. The principle of determining the thermal properties of materials is based on the transient temperature response generated by a disc-shaped heat source undergoing a stepwise heating in an infinite medium. A flat probe made of thermally resistive material serves as both a heat source and a temperature sensor. The thermal resistivity of the alloy shows a linear relationship with temperature and resistance, allowing for the determination of heat loss through changes in resistance, thereby reflecting the sample's thermal conductivity.

Product Features:

1. Wide-ranging testing scope with stable performance.

2. Direct measurement; test time can be set from 5 to 160 seconds, quickly and accurately measuring the thermal conductivity, saving a great deal of time.

3. Not affected by contact thermal resistance like the static method.

4. No special sample preparation is required; there are no specific requirements for the shape of the sample. For solid blocks, a relatively smooth surface is sufficient, and the length and width should be at least twice the diameter of the probe.

5. Non-destructive testing of samples ensures they are reusable.

6. The probe is designed with a double helix structure, combined with a proprietary mathematical model, and analyzes the data collected by the probe using core algorithms.

7. The sample stand features an ingeniously designed structure that is easy to operate, suitable for accommodating samples of varying thicknesses, and also boasts a simple yet elegant appearance.

8. The data collection on the probe utilizes imported data collection chips, which offer high resolution for more accurate and reliable test results.

9. The main control system employs an ARM microprocessor, which offers faster processing speed than traditional microprocessors, enhancing the system's analytical and processing capabilities, resulting in more accurate calculation results.

10. The instrument can be used for the determination of thermal properties of solid blocks, paste, granular solids, colloids, liquids, powders, coatings, thin films, thermal insulation materials, etc.

11. Intelligent human-machine interface with a color LCD display, touch screen control, easy and simple operation.
