Pt1000 wani resistor ne na zafin platinum, kuma ƙimar juriyarsa za ta canza tare da canjin zafin jiki. Lambar 1000 bayan "Pt" tana nuna cewa ƙimar juriyarsa ita ce 1000 ohms a 0°C, kuma ƙimar juriyarsa ita ce kusan 1758.56 ohms a 200°C. Darajar juriyar PT1000 tana ƙaruwa daidai gwargwado yayin da zafin jiki ke ƙaruwa. Pt100 kuma resistor ne na zafin platinum. Lambar 100 bayan "Pt" tana nuna cewa ƙimar juriyarsa ita ce 100 ohms a 0°C, kuma ƙimar juriyarsa ita ce kusan 175.86 ohms a 200°C. Pt500 kuma resistor ne na zafin platinum.

A zamanin yau, ana amfani da Pt1000 galibi don auna zafin jiki a cikin ma'aunin zafi ko calorimeters. Da farko, adadin kammala karatun Pt1000 ya fi girma, wanda ke haifar da daidaito mafi girma. Na biyu, impedance na shigarwa na Pt1000 ya fi girma, kuma ana iya ƙara ƙarfin kuzari, don haka yana inganta jin daɗin. Na uku, PT1000 ya dace da auna ƙananan canje-canjen zafin jiki (dalilin shine lokacin da zafin jiki ya canza da digiri ɗaya, canjin ƙimar juriya yana da girma sosai, kuma da'irar da ke gaba za ta iya gano shi cikin sauƙi). Dangane da amfani, Pt1000 shi ma ya fi dacewa. A aikace-aikacen filin masana'antu, gabaɗaya, ana canza siginar juriya na Pt100 da Pt500 zuwa siginar halin yanzu 4-20mA, sannan ana sarrafa siginar. Duk da haka, Pt1000 kai tsaye yana auna siginar juriya.
