For heavy-duty testing

The well-established TPS technique – today used in more than 1000 laboratories – is highly appreciated for its ability to simultaneously and quickly determine thermal conductivity, thermal diffusivity and specific heat capacity from a single measurement, with minimum sample preparation. Utilizing the unique Hot Disk sensors, the TPS 1500 system serves as a robust tool for testing the thermal properties of solids, powders, pastes and foams. If larger samples are available, also highly conducting samples, such as metals, semi-conductors and high-conductivity oxides, can be tested.

The TPS 1500 is designed as a reliable workhorse instrument for materials R&D within heavy-duty industries. The construction industry, for example, will see concrete and cement mixtures, woods, fibrous structures, and insulating materials readily and efficiently analysed. The Hot Disk Analysis software for the TPS 1500 system incorporates tools for automated measurements as well as automatic temperature control of external devices. In addition to the standard Isotropic and One-dimensional software modules the system can be extended with software to allow testing of anisotropic samples (Anisotropic module) and extremely light and low-conducting materials (Low-density/Highly-insulating module). Also available is a dedicated module for analysing specific heat capacity of solid samples, such as complex composites (Cp module).

The Hot Disk Thermal Analyser software for the TPS 1500 system incorporates tools for automated measurements as well as automatic temperature control of external devices. It also incorporates tools for exporting results to 3rd-party software (MS Excel), for additional processing or statistical analysis. For precise and automatic temperature readings an optional PT-100 temperature sensor is available.

Key Features

Sensors: The TPS 1500 operates a selection of Hot Disk sensors suitable for different materials and applications.

Temperature Control: Automatic Temperature series measurements (Isothermal Steps) are easy to perform using either an optional external Furnace or a temperature-controlled Circulating Bath. The Hot Disk Analysis software and TPS 1500 instrument controls the external device using RS-232 protocol.

Everything to get you started: The basic TPS 1500 setup includes everything you need to begin making measurements. The instrumentation includes: Software with standard isotropic module, one Sensor, Stainless Steel verification samples and a Room-Temperature Sample Holder.

Optional Software Modules: In addition to the standard ISOTROPIC and ONE-DIMENSIONAL modules, optional ones for ANISOTROPIC, SPECIFIC HEAT CAPACITY, and LOW-DENSITY, HIGHLY-INSULATING SAMPLES are available.
