Hot Disk TPS 2500 S is the leading instrument in the thermal properties industry, which can measure thermal conductivity, thermal diffusivity and specific heat (ISO/DIS 22007-2 compliant). TPS 2500 S can be used to test a large number of different types of materials, including solids. , liquids, powders and composites. It can also be used to test synthetic materials such as polymers, coatings, plastics, oils, substrate materials, nanomaterials, and liquids, gels, phase change or interface materials, as well as anisotropic materials such as fiber reinforcements and many more. Testing of layer materials. In addition, TPS 2500 S can also be used in high temperature superconductors, metal alloys, ceramics, rubber, additives, fabrics, glass, carbon and graphite materials. In addition, TPS 2500 S can be used in natural materials such as wood, grain, fluids, biological tissues, soil, rock, metals and minerals.




Many conventional industrial products can be classified as above, including continuous fine chemical products or building materials or conventional material composites such as paper, foam, film, insulation, protective film and spacers. All of these samples can be quickly measured using the TPS 2500 S, which is unique in the field of thermal properties testing. There are other testing methods on the market, but covering all of these categories inevitably requires the integration of several different instruments, which are costly, and all of these tests require only one instrument of the TPS 2500 S to be completed quickly and reliably.

Testing with the TPS 2500 S is very convenient and reliable. Simply attach a Hot Disk probe between two samples. The probe acts as both a heat source and a temperature sensor. The test process is very fast and accurate.




Users can also use the TPS 2500 S single-sided test module for inspection. At this point, the probe is fixed between a sample to be tested and another sample of known thermal conductivity, usually polystyrene. This option is widely used in the field of quality control. Compared to other single-sided technologies on the market, TPS technology provides both real-time and accurate thermal and thermal diffusivity.



For liquid, gel, and powder samples, simply insert the Hot Disk probe into the material or apply the material to both sides of the probe. For liquid testing, the Hot Disk is specially supplied with a liquid sample holder.



The latest feature of the TPS 2500 S is that the test time is increased to 1 second, which means that the temperature test record can be as small as 5 milliseconds. Due to this development, it is possible to test materials with a thermal conductivity of up to 400 W/(mK) using the basic module. In addition, the shorter test interval provides great convenience for testing very small liquids such as toluene and ethanol.
