M1 - Thermal Conductivity Meter

The Hot Disk M1 is a basic Thermal Conductivity Meter with high accuracy and measurement repeatability. With the M1, solids, powders and pastes in the thermal conductivity range of 0.03 to 40 W/m/K are readily tested. The sample size should be minimum 40 mm diameter (or square) and have a thickness of at least 10 + 10 mm. Larger samples are easily tackled without any further preparations than two parallel samples.

Operating the M1

The Hot Disk M1 is controlled from your iPad® via a Wi-Fi connection, or through USB cable and the optional PC software. The M1 constitutes a complete package with the core M1 unit, Hot Disk Kapton sensor (#8563, radius 9.9 mm), sample holder, verification samples of stainless steel and Wi-Fi transmitter. The iPad® software for thermal conductivity measurements is available free through the App Store. Measurement data can be stored and exported via DropBox® or iTunes®. 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.
