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.
