The tip shape (junction) can be selected from exposed type, installed type, and non-grounded type. For details such as sheath diameter, please refer to the "Sheath Thermocouple Series" on the link below: "Ishikawa Industry Thermocouple Sensor Product Site."

The operating temperature varies depending on the environment. For more details, please refer to the "High-Temperature Sheath Thermocouple Series" in the link below: "Ishikawa Industry Thermocouple Sensor Product Site."

It is a coaxial structure probe in which ultra-fine thermocouple wires are wrapped in a special ceramic insulator, coated on the surface with thermocouple material, and joined at the tip with a thickness of a few microns.

Ishikawa Sangyo has established a multi-vendor supply system for thermocouple-related products, in addition to a diverse and abundant inventory of its own, sourced from domestic and international manufacturers. We provide the best proposals to meet various requests such as "We are facing a parts shortage due to supply chain disruptions," "I need this thermocouple wire right now," "Is there a product equivalent to what we've been using?" and "What thermocouple is suitable for this thermal measurement?" ■ Please refer to our special website where we introduce the main items we handle. ■ In addition to the above, our website contains detailed information on various products and accessories, specifications, performance tables, etc. Temperature measurement using thermocouples requires knowledge and know-how. With over 60 years of experience and a track record of transactions with leading companies and research institutions both domestically and internationally, Ishikawa Sangyo will provide proposals tailored to your needs. If you have any concerns or questions regarding thermocouples, please feel free to consult us. We also offer a "Thermocouple Probe BTO Service," where we can process thermocouple wires to your desired specifications and lengths, as well as perform terminal processing such as attaching connectors and crimp terminals. We accept orders starting from small lots. Please consider this as well.

We will deliver thermocouples of your desired length and diameter with connectors or terminals attached. No complicated processing work like contact welding is necessary! You can start measuring temperature with the thermocouple immediately upon arrival of the product. Moreover, it's low cost! Feel free to request a quote from our website. We will respond via email within three business days after your request.
