TPS (Transient Plane Source) technology is a novel method for measuring thermal conductivity, developed by Professor Silas Gustafsson of Chalmers University of Technology in Sweden, based on the hot wire method. The principle of determining the thermal properties of materials is based on the transient temperature response of a disk-shaped heat source that produces 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 resistance coefficient of the alloy shows a linear relationship with temperature and resistance, meaning that by understanding the change in resistance, one can know the heat loss, thereby reflecting the sample's thermal conductivity properties.

Product Features:

1. Broad testing scope with stable performance.

2. Direct measurement; test time can be set from 5 to 160 seconds, allowing for quick and accurate determination of thermal conductivity, saving a significant amount of time.

3. Not affected by contact thermal resistance like static methods.

4. No special sample preparation is required; no specific shape is needed for the sample. Solid blocks only need a relatively smooth surface and dimensions at least twice the diameter of the probe.

5. Non-destructive testing on samples ensures they can be reused.

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

7. The sample stand boasts an ingeniously designed structure, easy operation, and is suitable for displaying samples of varying thicknesses. It is also simple yet aesthetically pleasing.

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

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

10. The instrument is suitable for measuring thermal properties of solid blocks, pasty solids, 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.

Software Features:

1. Supports instrument coefficient calibration.

2、Automatically calculates thermal conductivity, thermal diffusivity, and correlation coefficients, and can automatically determine if the results comply with temperature rise.

3. Curves can be easily adjusted with one click, zoomed in or out, and view dragged.

4. Supports opening multiple curves simultaneously, with no limit on the number.

5. Capable of generating reports, images, results, experimental information, etc., with customizable templates.

6. Software features built-in test record, data processing, and report formatting.

7、Accessable to data anywhere xls，tps,cvs,png Export in various formats, and supports for xls，tps,cvs Import in a specified format. The software features remote updates, enabling automatic acquisition of new software versions for direct installation.

8. Supports data optimization, data cleaning, and intelligent computation.

9. Supports Chinese, English, Switch between Japanese and Korean.
