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 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).
Advantages of the TPS technology as realized in the TPS 500:
- Pourous, transparent samples are easy to measure.
- Surface roughness or surface color does not influence measurement results.
- Contact pressure of sensor to sample surface does not influence measurement results.
- The method is non-destructive.
- Minimum- or no sample preparation (single-sided testing).
- Instant and fully consistent thermal conductivity results.
- Four thermal properties extracted from a single transient reading.
- No calibration or reference sample verification required (as it is an absolute technique).
Hot Disk® instrument users now number in the thousands world-wide. They appreciate our TPS technique for its unmatched measurement capability, together with its ease-of-use and effortless sample preparation. The operative simplicity of the TPS 500 instrument and the performance achieved when using optimally designed Hot Disk® sensors, makes the instrument uniquely suitable for QC applications, in particular automated production line QC via the capability of single-sided testing.
The test and analysis software (Hot Disk Desktop App) for the TPS 500 instrument incorporates tools for scheduled measurements as well as automatic ambient temperature control, using our temperature control unit accessories (e.g. Bath Circulator and Convection Oven). For precise ambient temperature readings an optional PT100 Temperature Sensor is available.
The TPS 500 test and analysis software also includes automated sensor switching functionality applying our Sensor Switch Unit accessories. It also incorporates tools for exporting measurement data and results to xlsx- or txt-files, for further processing or more advanced statistical analysis. With the optional Automation Module it is possible to remotely control the TPS 500 instrument. This facilitates isolation of the testing set-up from the operator, which is particularly useful for QC-testing at robotic controlled production line applications.
Key features
Simplicity: Our latest user friendly, yet sophisticated, test and analysis software simplifies testing, making the learning curve very short. Also, normally no sample preparation is necessary. This makes the TPS 500 a smart, simple-to-use tool, easy to integrate.
Rapidity: The TPS 500 will test most materials in less than 20 seconds. For multiple measurements on the same sample, a cooling time between tests is recommended.
Sensors: The TPS 500 includes two specially selected Hot Disk® sensors suitable for the specified range of materials and applications, with a respective radius of 3.2 mm and 6.4 mm.
Single-Sided Testing: When two pieces of a sample for optimized double-sided testing is not available, the included single-sided background insulation material can be used to measure on a single sample piece. This ability lends itself for QC operations at near-line or in-line production workflow.
Temperature Control: Using our test and analysis software, automatic series of measurements at different ambient temperatures (isothermal steps) are easy to perform using our optional Bath Circulator and Convection Oven accessories.
Everything to get you started: The basic TPS 500 configuration includes everything to get you started making measurements. The instrumentation includes the Isotropic and Single-Sided Testing Modules, two Hot Disk® sensors, a Stainless Steel verification sample for data verification, a single-sided background insulation for single-sided testing, and a room temperature sample holder (without protective hood).
Optional Measurement Modules: In addition to the included Isotropic and Single-Sided Testing Modules, the optional Automation Module is available for remote control of the TPS 500 instrument.

- 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.↩︎
