This PRT is ideal for applications where block calibrators, furnaces or temperature points are being used above normal PRT temperatures thanks to its -200 to 661°C range. With internal protection, the thermometer helps reduce the risk of contamination, and it measures 20in and comes equipped with INFO-CON connections for 914X models.
High-temp secondary standards fill the gap between temperature-limited secondary PRTs (platinum resistance thermometers) and highly accurate SPRTs (standard platinum resistance thermometers).
