The Fluke 724 Temperature Calibrator is a professional field-ready instrument engineered by Fluke Corporation – the worldwide benchmark in electronic measurement and process calibration tools. Designed as an all-in-one testing solution, the Fluke 724 empowers maintenance technicians, instrumentation engineers, and QA specialists to inspect, verify, and calibrate virtually all temperature instruments and transmitters throughout an entire industrial plant using a single, streamlined tool.

A standout capability of the Fluke 724 is its versatile measuring and sourcing architecture. The unit supports 12 thermocouple types (J, K, T, E, R, S, B, L, U, N, XK, BP) and 7 resistance temperature detector (RTD) types (Pt100-385, Pt100-392, Pt100-393, Pt100-JIS, Pt200, Pt500, Pt1000, and Ni120), in addition to measuring and sourcing DC volts (from mV up to 30V) and resistance (up to 3200 Ω). The instrument even handles high-speed pulsed RTD circuits. Its backlit dual-line display allows technicians to source a simulated temperature signal on the lower display while simultaneously monitoring the resulting loop current (mA) or voltage on the upper display, eliminating the need to toggle screens during loop verification.

Additionally, the Fluke 724 incorporates an integrated 24V DC loop power supply, allowing users to power field temperature transmitters directly while simultaneously reading their mA output. It features practical automated diagnostic functions, including 25% and 100% manual stepping for fast linearity tests, as well as automatic stepping and auto-ramping for remote verification. The intuitive "no-menus" interface provides dedicated pushbuttons for all primary functions, drastically reducing commissioning and testing times. Encased in Fluke’s signature rugged, impact-resistant holster and powered by 4 standard AA alkaline batteries providing up to 25 hours of operation, the Fluke 724 delivers lab-grade reliability under the most demanding field conditions.
