Temperature measurement head cylinder diameter 3mm, length 15mm, can be used with the heating block that support the thermocouple.   2. The temperature measurement range is increased from -50 ℃~ +250℃ to -50 ℃ ~ +350 ℃. It helps a lot to print high-temperature filament, can replace the original K-type thermocouple temperature. If need to print high-temperature filament, the HT-NTC100K thermistors are highly recommended.   3. The new version of HT-NTC100K temperature measuring thermistor adopts 304 stainless steel, with the internal temperature package to ensure the maximum service life with precision temperature measurement.   4. HT-NTC100K thermistor adopts whitehigh-temperature cord, can bear higher temperature. And for customers' convenience, the wires adopts line connection, the customer can tear the wires depends on their application. The high temperature line is double thicker than others in the market, not easy to break off.   5. Supports the customization of different specifications, including the temperature head cylinder size, length of the wires (MOQ is 100 sets).   6. Can be used with the new version of the heater (the new heater can heat up to 350 degrees).
