660°C Working standard PRTs

Model WSP660 PRTs are used our special wire wound RTD elements, assembled into Inconel probes. WSP660 series have similar accuracy and long-term stability of SSP670 secondary standard PRTs. They can be used for calibration furnaces, sand bath and other calibration work. Available in standard models and custom design.
