- Upgrade from the original ordinary temperature probe directly exposed temperature measurement to resistance package temperature measurement. Temperature measurement head cylinder diameter 3mm, length 15mm, can be used with the heating block that supports the thermocouple.
- The temperature measurement range is increased from -50 ℃~ 250℃ to -50 ℃ ~ 320 ℃. It helps a lot to print high-temperature filaments and can replace the original K-type thermocouple temperature. If need to print high-temperature filament, the HT-NTC100K thermistors are highly recommended.
- 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.
- HT-NTC100K thermistor adopts a white high-temperature cord, which can bear higher temperatures. And for customers’ convenience, the wires adopt line connection, the customer can tear the wires depending on their application. The high-temperature line is double thicker than others in the market, not easy to break off.
- Supports the customization of different specifications, including the temperature head cylinder size, and length of the wires (MOQ is 100 sets).
- Can be used with the new version of the heater (the new heater can heat up to 350 degrees).

Frequently Asked Questions
Can I use this thermistor in place of a K-type thermocouple?
Yes. Simply connect the 2-pin JST plug to your controller’s thermistor port and select the 100 KΩ B3950 profile in firmware. It delivers stable readings without the wiring complexity of K-type sensors.
Do I need to calibrate the sensor before use?
No calibration is required. The thin-film B3950 element is factory-matched to ±1% accuracy—just select the matching curve in your controller settings for plug-and-play operation.
What is the safe operating temperature range?
The stainless-steel probe and high-temp cable support continuous operation up to 320 °C, with reliable measurements down to −40 °C in low-temperature environments.
