Hyoda’s journey began with the development of temperature control technology. Since its founding in 1917, the company has been dedicated to advancing and manufacturing thermometers and various measurement and control devices. Originating in Osaka, Hyoda now provides a wide range of heat control technologies to customers both in Japan and internationally. Hyoda-branded measuring instruments are widely used across heavy industries (such as heavy electrical equipment, nuclear power plants, ships, and petrochemical facilities), light industries (including textiles, dyeing, and food production), as well as household products (like microwave ovens and cookware).
