About 300 thermal constant measuring systems have been installed in the field since this system was put on the market in 1970 and are highly valued for excellent performance in various fields of application. This system was standardized by the Japanese Industrial Standards (JIS R 1611-1977) as a thermal diffusivity and specific capacity measuring system for fine ceramics. It is complete with a substrate measurement attachment for a 1-inch square sample and a stepwise heating attachment for a heterogeneous compound sample.

This instrument measures the thermal conductivity of thin film on order of submicron deposited on a substrate from the measurement results of apparent thermal diffusivity of deposited sampling substrate and the thermal diffusivity of sampling substrate alone using the scanning laser heating AC method (Angstrom method).

The FTC-1 measures thermal diffusivity in the normal direction of polymer, paper and ceramic thin sheet samples using the periodical Joule heating method. It conforms to polymer film ISO 22007-3.
