The Fluke 724 Temperature Calibrator simultaneously measures and sources temperature signals across RTD, thermocouple, voltage, current, and resistance parameters. Designed for field and laboratory temperature sensor verification, it delivers calibration-grade accuracy with straightforward operation and dual-line display output. The instrument supports 10–12 thermocouple types (J, K, T, E, L, N, U, B, R, S, XK, BP) and 7 RTD variants (Ni120, Pt100 385/393/JIS/3926, Pt200, Pt500, Pt1000), plus DC voltage, current, and resistance measurement and sourcing functions.
