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

The 7Semi PT100 RTD Temperature Sensor Probe (3-wire, 3m) is a high-accuracy temperature sensing device designed for precise measurement across a wide temperature range from -70°C to +300°C. It uses a platinum resistance element (PT100) that provides excellent linearity, repeatability, and long-term stability. The 3-wire configuration minimizes lead resistance error, ensuring accurate readings even over longer cable distances. Enclosed in a durable stainless-steel probe with a 3-meter cable, this sensor is ideal for industrial, laboratory, and environmental temperature monitoring applications.
