Thermal conductivity tester uses the transient plane source technique (TPS). Test performance is stable and data processing and analysis capability is high, can be used for thermal conductivity measurement of a variety of different types of materials.
Measurement objects
Material Type: metals, ceramics, alloys, minerals, polymers, composites, paper, fa bric, foam (flat surface insulating materials, sheet metal), polyurethane, phenolic, urea-formaldehyde, mineral wool (glass wool, rock wool, mineral wool), cement walls, glass reinforced composite panels CRC, cement polystyrene plates, sandwich concrete, glass and steel panels composite plates, paper honeycomb panels.
Features of thermal conductivity tester
- Test range is wide and the test performance is stable. It is at the priority level among similar domestic instruments;
- Direct measurement, the test time can be set about 5-160s, which can quickly and accurately measure the thermal conductivity, saving a lot of time;
- Will not be affected by contact thermal resistance like static method;
- No special sample preparation is required, and there are no special requirements for the shape of the sample. The bulk solid only needs to have a relatively smooth sample surface and meet the length and width of at least twice the diameter of the probe;
- Non-destructive testing of samples means that the samples can be reused;
- The probe is designed with a double helix structure, combined with the exclusive mathematical model, and the core algorithm is used to analyze and calculate the data collected on the probe;
- The structure design of the sample table is ingenious, easy to operate, suitable for placing samples of different thicknesses, and at the same time simple and beautiful;
- The data acquisition on the probe uses an imported data acquisition chip. The high resolution of the chip can make the test results more accurate and reliable;
- The control system of the host uses an ARM microprocessor, which has a faster calculation speed than traditional microprocessors, improves the analysis and processing capabilities of the system, and makes the calculation results more accurate;
- The instrument can be used for the determination of thermophysical parameters such as block solids, paste solids, granular solids, colloids, liquids, powders, coatings, films, and thermal insulation materials;
- Intelligent man-machine interface, color LCD screen display, touch screen control, convenient and simple operation;
- Powerful data processing capabilities. Highly automated computer data communication and report processing system
