Overview
The ai-Phase Mobile M3 type1 is built for precise thermal diffusivity analysis where conventional approaches are often difficult to apply, especially for thin films, foils, coatings, and other small-format samples.
Using Temperature Wave Analysis (TWA), the system evaluates heat transport behavior from phase delay in a controlled temperature wave, enabling stable and reproducible measurements across a broad material range.
Developed from ai-Phase expertise in micro- and nano-scale thermal characterization, Mobile M3 type1 combines compact hardware, low power consumption, and user-friendly operation. The result is a practical instrument for laboratories and R&D teams that need reliable thermal transport data without long setup procedures or complex sample preparation.
