C-Therm Supplies Thermal Conductivity Testing Solutions for R&D, Manufacturing, Polymers, and More

Established in 2007, C-Therm Technologies provides sensor solutions for R&D, manufacturing and quality control environments, offering the latest in rapid, non-destructive thermal analysis instrumentation. The company was launched with the acquisition of the assets of Mathis Instruments and is privately held within the Cartmill Group of Companies.

C-Therm Technologies sensor systems offer thermal analysis of the following material properties:

  • Thermal Conductivity
  • Thermal Effusivity
  • Thermal Inertia

And can test for material consistency, homogeneity, layering, abnormalities.

The technology, which represents a paradigm shift in thermal conductivity measurement, earned the inventor the top award for innovation in Canada (Manning Award). The technology has also won numerous other awards including the R&D 100 award. This coveted international distinction is given to the top 100 innovations worldwide, and puts the sensor technology in the distinguished company of other winners, including the ATM, Polaroid film, and anti-lock brakes.
