7SEMI PT100 RTD Temperature Sensor Probe 3-wire 1m -70~300C

The 7Semi PT100 RTD Temperature Sensor Probe (3-wire, 1m, -70~300°C) is a precision resistance temperature detector designed for accurate temperature measurement in industrial, laboratory, and environmental applications. Based on a platinum RTD element with 100 Ω resistance at 0°C, this probe offers excellent linearity, repeatability, and long-term stability. The 3-wire configuration helps eliminate lead resistance errors, ensuring high measurement accuracy even over longer distances. Enclosed in a stainless-steel sheath with a 1-meter cable, the sensor provides reliable and stable performance across a wide temperature range.
