The world's most popular, innovative and accurate loop calibrators


Fluke offers the widest variety of mA calibration and test tools in the industry to address virtually all types of mA loop testing. The Fluke 709H combines HART communication with 0.01% best in class accuracy mA measurement and sourcing. The Fluke 773 mA clamp meter can measure 4 to mA signals without breaking the loop and has a mA loop and V dc source built in. The Fluke 789 ProcessMeter features a multimeter and loop calibrator in one tool. Perform calibration/testing on the bench top (or anywhere the transmitter is not powered) with the on-board 24V power supplies. All these loop calibrators share a common user interface making the training on new tools faster across the whole team.


Fluke Connect Wireless Test Tools put tools, not your body, near live electrical panels. It's simple. By equipping a Fluke Connect compatible mA loop calibrator with a temperature measurement module and the wireless data logging capabilities of Fluke Connect®; with ShareLive™ video call (sold separately), process technicians can now do a lot more while carrying a lot less. And with its built-in, selectable 250 ohm HART® resistor, it eliminates the need to carry a separate resistor with you.

Better still, the Fluke Connect test tools can send measurement data to your smartphone, so you can save and share measurements from the field with your team anytime, from anywhere.
