Fluke 789 ProcessMeter™ (Fluke-789): 100% Genuine Global Supply for Dual-Function Loop Calibration & Multimeter Diagnostics
The Fluke 789 ProcessMeter™ is the ultimate troubleshooting tool for process technicians, combining a full-featured 1000V CAT IV safety-rated True-RMS digital multimeter with a 24V loop power supply and loop calibrator in a single, rugged handheld instrument. By integrating a built-in 250-ohm HART® resistor directly into the meter, the Fluke 789 eliminates the need to carry a separate resistor when configuring and calibrating HART smart transmitters.
As a trusted global B2B supplier, we guarantee that every Fluke 789 ProcessMeter we export is 100% original, brand new, and factory-sealed, offering absolute quality assurance alongside highly competitive international wholesale pricing for industrial facilities worldwide.
Key Features & Product Highlights
-
24 V Loop Power Supply: Powers 2-wire field transmitters directly during offline testing, eliminating the need to carry external power packs to remote field sites.
-
Built-In 250 $\Omega$ HART Resistor: Dedicated loop power mode includes a selectable 250 ohm resistor so you can communicate seamlessly with HART field devices without wiring additional resistors into the circuit.
-
Full-Featured True-RMS Digital Multimeter: Measures AC/DC voltage up to 1000 V, AC/DC current up to 440 mA, resistance, continuity, and frequency up to 20 kHz.
-
20 mA DC Current Source & Loop Calibrator: Sources, simulates, and measures 0–20 mA or 4–20 mA current signals with 0.05% accuracy and 1 $\mu\text{A}$ resolution.
-
Span Check & Step/Ramp Functions: Features 0% and 100% buttons to quickly toggle between 4 and 20 mA for fast span checks, as well as automatic slow ramp, fast ramp, and step outputs.
-
Enhanced Display & Safety: Dual-display backlight shows mA and percentage of scale simultaneously, backed by CAT III 1000V / CAT IV 600V safety overvoltage protection.
