Resistance thermometers, also called resistance temperature detectors (RTDs), are sensors used to measure temperature. Many RTD elements consist of a length of fine wire wrapped around a heat-resistant ceramic or glass core but other constructions are also used. The RTD wire is a pure material, typically platinum (Pt), nickel (Ni), or copper (Cu).

RTDs - or Resistance Temperature Detectors - are temperature sensors that contain a resistor that changes resistance value as its temperature changes. The most popular RTD is the Pt100.

Thank you for purchasing your REED C-370 RTD Thermometer. Please read the following instructions carefully before using your instrument. By following the steps outlined in this manual your meter will provide years of reliable service.

An RTD sensor measures temperature by correlating the resistance of the sensor element with temperature changes. Made from pure metals like platinum, RTDs provide accurate and stable readings, making them ideal for industrial, laboratory, and environmental temperature monitoring.

These resistance elements are the heart of Resistance Temperature Detectors (RTDs). Generally, a bare resistance element is too fragile and sensitive to be used in its raw form, so it must be protected by incorporating it into an RTD (Pt100 or Pt1000).
