TPS 500 S

The Hot Disk® TPS 500 S is a compact TPS solution for small labs and QC environments, delivering rapid measurement of Thermal Conductivity, Thermal Diffusivity, Thermal Effusivity and Specific Heat Capacity across a broad range of sample types.

Overview

The Hot Disk® TPS 500 S rapidly and accurately measures the Thermal Conductivity, Thermal Diffusivity, Thermal Effusivity and Specific Heat Capacity of a wide range of materials and is therefore an excellent step-in thermal conductivity meter, and uniquely suitable for QC testing. The TPS 500 S adds powerful new features to the 500-series, in accommodating e.g. more measurement modules and sensor models. The TPS 500 S can handle bulk sample sizes down to a thickness of a few millimeters, has a Thermal Conductivity range of 0.03 to 200 W/m/K, and its temperature span is from -100°C to 300°C. It is partly based on ISO 22007-2* and ASTM E3088-25*, and is CE marked.

For the small-scale lab

The compact Hot Disk TPS 500 S Thermal Constants Analyser rapidly and precisely measures the Thermal Conductivity, Thermal Diffusivity, Thermal Effusivity and Specific Heat Capacity of a wide range of materials and is therefore a powerful thermal conductivity meter for the small-scale laboratory or QC testing set-up.

The TPS 500 S instrument condenses our patented and powerful TPS technology (now ISO and ASTM standardised) with our elegant test and analysis software, arguably resulting in the simplest-to-use and versatile thermal conductivity meter on the market.

The TPS 500 S measures the Thermal Transport Properties of solids, powders, pastes, gels and liquids over a temperature range of -100°C to 300°C. The instrument 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 and ASTM E3088-25).

  1. Hot Disk AB reserves the right to make changes without prior notice, whether due to misprints, improved hardware, or extended software capabilities.
  2. Time of transient temperature reading. An additional temperature settling time that depends on the sample material and TCU (if applied) is required to ensure isothermal condition before the reading.
  3. Comparing measurements performed by different instrument set-ups.
  4. Variation in consecutive measurements performed by a single instrument set-up. Note that this value depends on sample material, sensor model, and sample temperature.
  5. Standard deviation in fitting ∆Τ(τ)-function to the transient temperature reading. Note that this value depends on sample material, sensor model, sample temperature, and can vary considerably.
