Pt1000 wani resistor ne na zafin platinum wanda ƙimar juriyarsa ta bambanta da zafin jiki. "1000" bayan "Pt" yana nufin yana da juriya na ohms 1000 a 0°C da kuma kimanin 1758.56 ohms a 200°C. Resistor na PT1000 yana ƙaruwa a hankali yayin da zafin jiki ke ƙaruwa. Pt100 kuma resistor ne na zafin platinum, tare da "100" yana nuna juriya na ohms 100 a 0°C da kuma kusan 175.86 ohms a 200°C. Pt500, wani resistor na zafin platinum, yana da juriya na ohms 500 a 0°C da kuma kusan 879.30 ohms a 200°C.
A halin yanzu, ana amfani da Pt1000 sosai don auna zafin jiki a cikin ma'aunin zafi. Da farko, Pt1000 yana da babban digiri, wanda ke ba da damar yin daidai. Na biyu, babban ƙarfin shigarwa yana ba da damar ƙara ƙarfin kuzari, yana ƙara ƙarfin ji. Na uku, PT1000 ya dace don auna ƙananan bambance-bambancen zafin jiki (tunda canjin zafin jiki na digiri ɗaya yana haifar da babban canjin juriya, yana sauƙaƙa gano da'irar da ke gaba). Dangane da aikace-aikacen, Pt1000 ya fi dacewa da mai amfani. A cikin saitunan masana'antu, siginar juriya na Pt100 da Pt500 yawanci ana canza su zuwa siginar halin yanzu 4-20mA don ƙarin sarrafawa, yayin da Pt1000 ke auna siginar juriya kai tsaye.
