Distributor

Hayashi Denko

Specializes in industrial temperature measurement equipment, manufacturing and supplying resistance temperature detectors (RTDs), thermocouples, radiation thermometers, and temperature converters, including proprietary wound and thin-film RTD element technology. Operating since 1961 from Tokyo with an additional production facility in Shizuoka, the company primarily serves the domestic Japanese market while also offering custom sensor fabrication, calibration, and technical selection support rather than functioning as a general-line catalog distributor.
