Controlling all "temperatures" in the world. With the high technological capabilities and reliable trust cultivated as the "TOHO" of temperature, we respond to our customers' needs. Since our founding, temperature control devices and temperature sensors have evolved alongside changes in the times, and we have always focused on the development of new products. Under the philosophy of "creating technology," we are also actively engaged in the development and manufacturing of various control devices to meet a wide range of requests from customers, separate from temperature control and temperature sensors. In the manufacturing of probe cards, which are essential as inspection tools in semiconductor manufacturing processes, we are committed not only to meeting customer demands for multi-pin and narrow pitch configurations but also to providing quick turnaround times.
