Techne - PRT`s 300° C Working Standard PRT Features Techne PRT's The model TI913 RTD is a good choice for lower temperature range work at a lower accuracy. The sheath is of stainless steel construction with a mineral insulated .385 alpha RTD. The TI913 can be used as a working standard in calibration baths, furnaces, fluidized baths, dry block calibrators or for any other temperature calibration work. 660° C Working Standard PRT Model WSP660 PRTs are assembled using our special wire wound RTD elements, assembled into inconel sheaths. The WSP660 PRT has similar accuracy and long-term stability specifications you would find in much higher priced Primary standard PRTs. The WSP660 PRT can be used as a reference standard in calibration baths, furnaces, fluidized baths, dry block calibrators and other any other temperature calibration work requiring a high level of accuracy and repeatability. Combine with Specifications Specifications Specifications Resistance at 0° C: 100 ohms Temperature range: -20 to 300°C Temperature coefficient: 0.00385 O /O /° C minimum Stability: Meets IEC stability specifications after 250 hours exposure to extremes of temperature range. Typical drift is less than 0.05°C (0.02O) at 0°C. Repeatability: Meets IEC requirements. Typical shift less than 0.05°C (0.02O) at 0°C after ten cycles over range. Dimensions: 0.25" dia. x 12" L inconel sheath as standard, custom sizes available Tolerance at 0° C: ± 0.06%, IEC DIN class A Lead Wires: 4 wire Teflon insulated, stranded 22 AGW copper x 6' L Calibration Each WSP660 includes an ITS-90 NIST traceable calibration with a+, b+, a- and b- coefficients and R vs T table.
