The Fluke A3004 FC DC 20 A Current Clamp is a low-current wireless module designed for UK electricians, control engineers and maintenance technicians who need precise DC current measurement on 4–20 mA control loops and instrumentation circuits.
Unlike the larger Fluke A3003 FC, which measures heavy DC loads up to 2000 A, the A3004 FC focuses on accurate small-signal diagnostics, making it ideal for process control, PLC testing, and automation systems.
Fully compatible with the Fluke 3000 FC Multimeter and other Fluke Connect® tools, it lets you capture, log and share live DC readings remotely via smartphone or tablet for faster, safer and smarter maintenance.
How does the A3004 FC simplify your workflow?
By pairing wirelessly with the Fluke Connect app, you can take readings in tight or hazardous areas without holding a meter. View and record data from a distance, compare live trends and generate instant reports, saving time during every inspection or calibration task.
