Hot Disk® Instrument TPS 3500 Model：TPS 3500

The Hot Disk TPS 3500 is the state-of-the-art instrument for testing the Thermal Conductivity, Thermal Diffusivity, Thermal Effusivity and Specific Heat Capacity of tiny, highly thermal conducting samples. The capabilities of the TPS 3500 go well beyond that of any other available instrument to date – Thermal Conductivity ranging from 0.005 to 1800 W/m/K, tackling 10-micrometer-thick slab samples, and accommodating temperatures from cryogenic to 1000ºC. It has also the unique ability to analyse the anisotropic thermal transport properties of both uniaxial and biaxial materials, by use of specialized Hot Strip sensors in the latter case. The TPS 3500 meets ISO 22007-2 and is CE marked.

∎ Features

Sensors

The TPS 3500 operates a wide variety of Hot Disk sensors. With sensor radius from 0.5 mm up to 30 mm the instrument is suitable for all kinds of materials and applications. Multiple sensors can be connected using an automatic sensor switcher. With sensor radius from 0.5 mm up to 30 mm the instrument is suitable for all kinds of 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. These external devices can be directly controlled through the Hot Disk Thermal Analyser software to ensure ease of use.
Everything to get you started: The basic TPS 3500 setup includes everything you need to begin making measurements. The system includes: Hot Disk TPS 3500 instrument; Isotropic, One-dimensional and Structural Probe measurement modules; a Sensor; Insulating Support-Material for Single-Sided testing; Stainless Steel Verification Samples and Room-Temperature Sample Holder.
Optional Software Modules
