Hot Disk M1

For the slim budget

The Hot Disk M1 can test thermal conductivity and diffusivity of modestly sized isotropic samples, with a minimum diameter (or square) of 40 mm and a thickness of at least 10 + 10 mm. Larger samples are easily tackled without any further preparations than one plane surface on each of the two sample specimens, to sandwich the sensor between. It is also possible to test single sample pieces using an insulating sensor support.

The Hot Disk M1 is controlled from the same powerful Windows based software used for Hot Disk’s more advanced instruments. This gives access to in-depth data analysis not commonly seen for instruments in this class. Optionally, the Hot Disk M1 can be operated via a wireless connection through a RS-232 to WiFi adapter, allowing maximum portability. The M1 constitutes a complete package with the core M1 unit, a Hot Disk Kapton sensor (#8563, radius 9.9 mm), sample holder, verification samples of stainless steel and Windows software. Additional WiFi accessory is now available upon request.

The simplicity of the M1 device and the quick-start guide makes it possible to begin measurements within minutes. To further add to its flexibility, the compact design of the M1 instrument makes it easy to move between measurement stations or other locations of interest.

TPS 3500

For testing the extreme

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.
