The Fluke 715, 707, and 705 Loop Calibrators are a trio of rugged, reliable tools designed to make current loop calibration and troubleshooting a snap for technicians. The Fluke 715 stands out with its ability to measure and source both 0-20 V and 0-24 mA with a stellar 0.01% accuracy, plus a 24 V loop supply for powering loops while measuring. The Fluke 707, with its one-handed “Quick Click” knob, delivers 0.015% accuracy, a built-in 250-ohm HART resistor, and 0-28 V measurement, making it a speedy choice for loop checks.
The Fluke 705 offers a budget-friendly option with 0.02% accuracy and essential features like simultaneous mA and % span display. All three provide 24 V loop power, auto step/ramp, and SpanCheck for quick 4-20 mA toggling, housed in compact, dust/splash-resistant cases that shrug off 1-meter drops. With 18-hour battery life from a 9 V alkaline battery and a three-year warranty, these calibrators are built for precision and portability, offering tailored solutions for process loop maintenance with a dash of user-friendly efficiency.
