RTDs - or Resistance Temperature Detectors - are temperature sensors that contain a resistor that changes resistance value as its temperature changes. They have been used for many years to measure temperature in laboratory and industrial processes, and have developed a reputation for accuracy, repeat-ability, and stability. Temperature Range -50 ~ 200°C (-58 ~ 392°F) Size: Probe head 4 mm x 30 mm Length : 2000 mm, 2 Meters (long) Tolerance of PT100 Ω (Alpha = 0.003850 @ 0oC) , Class A : ± 0.06 Ω OR ± 0.15oC 4 wire connection is the most accurate measurement. The instrument measures the lead resistance of all four lead wires removing these values for its reading
