This 5626-20-L 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 mini spade lug connections. High-temp secondary standards fill the gap between affordable, but temperature-limited secondary PRTs (platinum resistance thermometers) and more expensive, highly accurate SPRTs (standard platinum resistance thermometers).
