Product Information

Fluke 789/773 BU 789 Process Meter and 773 Milliamp Process Meter Bundle Package

Fluke 789 Process Meter with 250 Ohm HART Resistor

What do you get when you take the Fluke 787, the original combination multimeter and extend the range? You get the Fluke 789, ultimate loop calibration multimeter with very large dual display. The 789 goes one step further in battling low light conditions by adding two brightness settings to the enhanced backlight. This precision 1000 V, 440 mA and True-RMS digital multimeter does it all and includes diode test and continuity beeper. The externally accessible AA alkaline batteries last a typical 140 hours in measurement mode and are easy to change in the field. So let this powerful two in one multimeter be the only tool you need.

Double Your Power

The Fluke 787 was the first tool to combine a DMM and a loop calibrator to give process technicians double the power in one tool. Now it’s even better, the range is extended with the new Fluke 789 – the ultimate loop calibration multimeter. The Fluke 789 has a 24-Volt loop supply reducing the need for taking a separate power supply when doing offline transmitter testing. And with its built-in, selectable 250-Ohm Hart® resistor, it also eliminates the need to carry a separate resistor with you. Now process technicians can do a lot more while carrying a lot less.

Safety Conformance

Meets 1000 Volt EN61010-1 CAT III standards and 600 Volt EN61010-1 CAT IV standards

Fluke 773 Milliamp Process Clamp Meter

Need more hours in your day?

Save time by NOT breaking the loop on 4-20 mA signal measurements.

Are you spending time:
Taking mA measurements by removing a wire and breaking the loop Calling the control room to isolate a loop Testing analog input/output on a console Troubleshooting devices with mA inputs and outputs Repairing intermittent or erratic 4-20 mA loops Going back to the shop to get extra tools

If you need more time in your busy day take a good look at the Fluke 773 mA Clamp Meters. It’s designed to save you time, and money, by eliminating time wasting activities. Now you can troubleshoot and repair 4-20 mA loops without breaking the loop or bringing down the system.
