Basic Thermal Constants Analyser

The Hot Disk TPS 500 Thermal Constants Analyser rapidly and accurately measures thermal conductivity, thermal diffusivity and specific heat capacity of a wide range of materials. This economical instrument condenses the powerful TPS technology with elegant analysis software, arguably resulting in the simplest-to-use thermal conductivity testing apparatus on the market.

The TPS 500 measures the thermal transport properties of solids, pastes, gels and powders and encompasses similar accuracy and sample size flexibility as the benchmark TPS 2500 S and workhorse TPS 1500 (the latter two instruments are designed according to ISO 22007-2).

Hot Disk users now number over 600 world-wide. They appreciate the TPS technique for its unmatched measurement capability, together with its ease-of-use and simple sample preparation. The operative simplicity of the TPS 500 and the performance achieved when using Hot Disk sensors, makes the instrument uniquely suitable for QC testing.

The test & analysis software for the TPS 500 system incorporates tools for automated measurements as well as automatic temperature control of external devices. The software also incorporates tools for exporting results to third-party software (MS Excel), for additional processing or statistical analysis.

The advantages of using a TPS instruments involve the following:

The method is non-destructive.

Contact resistance between sensor and sample does not influence measurement results.

Porous and transparent samples are easy to test, without modification.

Surface roughness or surface color does not influence measurement results.

Minimum- or no sample preparation.

Double-sided testing for maximum accuracy.

Optional single-sided QC-testing for maximum ease.

Instant and fully consistent thermal conductivity results.

Three thermal transport properties measured in a single transient.

No calibration or reference sample verification required. (The TPS technique is an absolute technique.)

Thermal Testing Laboratories: The Transient Plane Source (TPS) series of thermal conductivity systems are well suited for thermal testing laboratories due to their superior material type, sample size and temperature flexibility.

Nanotechnology: Nano-Research is the creation of high performance functional materials, devices and systems through control of matter on the nanometer length scale. The TPS series of thermal conductivity systems are particularly well suited for the testing of nano-engineered materials, whether your interests are in solids or liquids. One highlight is the electrically insulated TPS sensors, which are key to accurately measuring the thermal conductivity of liquids, without the negative influence of nano-particle + non-insulated metal sensor the more traditional methods suffer from.

Building Materials: With the ability to measure homogenious and non-homogenious materials, the TPS thermal conductivity systems can be used to test all building materials from insulation to concrete and everything in between.

Heat Transfer Materials: Uniquely designed to test heat transfer materials of all types, including solids, liquids and pastes. The TPS Thermal Conductivity Systems are also able to test complex heat transfer samples such as thin films and higly conductive sheets. For anisotropic samples, the TPS can measure directional thermal conductivity through the thickness and in the plane.

Geothermal: Thermal Conductivity is an ever increasing property to understanding the geothermal industry. Widely used for its ability to test samples like soil and rock with temperature, the TPS thermal conductivity instrument continues to play an important part in this growing industry.

Solids: Offering the best combination of accuracy and testing flexibility, the TPS thermal conductivity systems cover a wide range of thermal conductivity (0.001 to 500 W/mK). Added to this flexibility is the ability to test composites, thin films and anisotropic solids.

Liquids: The TPS thermal conductivity systems can be used to test liquids under conditions of minimised volume, temperature and pressure. The electrically insulated TPS sensor offers several advancements over the typical bare metal sensors, such as protection from particle interference and convection effects.

Powders: Whether your particles are small or large in size, the TPS thermal conductivity system offers several sensor sizes to accomadate the individual particle or bulk sample.

Pastes: Combining the ability to measure semi-solids and high thermal conductivity, make the TPS thermal conductivity system a perfect tool for measuring pastes.
