Fluke 709 Precision mA Loop Calibrator
Model No :
Fluke 709
Part Code :
4.23435e+006

Overview

The Fluke 709 mA loop calibrator reduces the time it takes to measure or source voltage or current and power up a loop and still produce high-quality results. It's built around a user friendly interface with a quick-set rotary encoder knob and best in class accuracy at 0.01% of reading.

Features
- mA precision loop calibrator with best-in-class accuracy at 0.01% reading
- Provides intuitive user interface with quick-set rotary encoder knob for fast setup
