It has excellent durability across a wide range of variations, from extremely low temperatures to high temperatures.

In the HT series of temperature sensors with thermocouples, we offer a wide variety of thermocouple types, sheath materials, and terminal types. For sheath thermocouples, we can manufacture sheath outer diameters ranging from Ф0.25mm (thin diameter) to Ф12mm. Additionally, we can also produce special-shaped thermocouples such as protection tube types and duplex types, allowing you to choose the optimal thermocouple for your application. The measurable temperature range covers a wide spectrum, from ultra-low temperatures of -269°C (gold-iron-chromel) to high temperatures of 1600°C (platinum-rhodium-platinum), making it the highest temperature capable of being used as a contact-type temperature sensor. The sheath materials include two types: SUS316, which excels in heat resistance, corrosion resistance, pressure resistance, and impact resistance, and NCF600. Furthermore, we can also manufacture ceramic pipes and titanium as protection tubes. We have many other thermocouple products available as well. For more details, please contact us through our company website or refer to our catalog.
