Features Resistance encapsulated temperature measuring head, temperature measuring head cylindrical outer diameter of 3mm / 0.1in, length of 15mm / 0.6in, can be used with the heating block supporting thermocouple. From the original temperature range of ‑50℃ to +250℃ increased to ‑50℃ to +350℃, help to print high temperature materials. 304 Stainless steel material manufacturing to achieve the maximum service life and accurate temperature measurement. Adopts white high‑temperature wire soft wire, which is more high‑temperature resistant, adopts parallel wire connection. Can tear it to use according to needs. The high‑temperature wire is thick and it is not easy to break.
