660°C Working Standard PRTs
Model WSP660 PRTs use our special wire wound RTD elements assembled into inconel probes. They have similar accuracy and long-term stability as SSP670 secondary standard PRTs. They can be used for calibration of furnaces, sand bath and other calibration work. Available in standard models and custom design.
