Fluke 709H Precision Current Loop Calibrator

Overview

The Fluke 709H is a precision current loop calibrator designed for field technicians and service professionals. It combines industry-leading 0.01% reading accuracy with a compact, rugged design powered by standard AAA batteries. The instrument features intuitive operation with a Quick-Set knob for rapid setup and includes built-in HART communication via a selectable 250Ω resistor. The 24 V DC loop power with mA Measure Mode enables comprehensive loop testing from -25% to 125%, while the Valve Test feature allows simulation of defined mA values for system diagnostics.
