The improvements compared to the other temperature resistance in the market: 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 support the thermocouple. The temperature measurement range is increased from -50 Celsius ~ +250 Celsius to -50 Celsius ~ +350 Celsius. 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. The new version of HT-NTC100K temperature measuring thermistor adopts 304 stainless steel, with the internal temperature package to the maximum service life with precision temperature measurement. HT-NTC100K thermistor adopts white high-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. Supports the customization of different specifications, including the temperature head cylinder size, length of the wires. Can be used with the new version of the heater (the new heater can heat up to 350 degrees). Thermistor temperature measurement is stable. The temperature measurement of the upgraded HT-NTC100K can be up to 350 degrees, can effectively replace the K-type thermocouple. It helps much to solve the issues of requirements of K-type thermocouple wiring, and is long which is susceptible to get external interference and result in temperature fluctuation that can affect the printing quality. Model: HT-NTC100K thermistor temperature sensor components Negative Temperature Coefficient (NTC)Thermistor Model: B3950 Temperature measurement head size: 3 * 15mm Material: ABS colour: white Length: 1 M Package Contents: 1* Thermistor Temperature Sensor Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
