Overview
The Hot Disk® TPS 500 swiftly and accurately measures the Thermal Conductivity, Thermal Diffusivity, Thermal Effusivity and Specific Heat Capacity of a wide range of materials. It is therefore a favorable step-in thermal conductivity meter, and highly suitable for QC testing. The TPS 500 can handle bulk sample sizes down to a thickness of a few millimeters. The TPS 500 Thermal Conductivity range is from 0.03 to 100 W/m/K, and its temperature range from -100°C to 200°C. It is partly based on ISO 22007-2* and ASTM E3088-25*, and is CE marked.

For the economical lab
The accessible Hot Disk® TPS 500 Thermal Constants Analyser quickly and accurately measures 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 for the economical laboratory or QC testing set-up.
The TPS 500 instrument condenses our patented and now ISO and ASTM standardised TPS technology with our user-friendly test and analysis software, resulting in a smart, simple-to-use thermal conductivity meter.
The TPS 500 measures the Thermal Transport Properties of solids, powders, pastes, gels and liquids over a temperature range of -100°C to 200°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).

- Hot Disk AB reserves the right to make changes without prior notice, whether due to misprints, improved hardware, or extended software capabilities.
- 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.
- Comparing measurements performed by different instrument set-ups.
- Variation in consecutive measurements performed by a single instrument set-up. Note that this value depends on sample material, sensor model, and sample temperature.
- 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.
