For the small-scale lab

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 S 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 1000 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 S 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 S 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.
