Remote Display Clamp Meter for Solo Technicians

The Fluke 381 combines a True-RMS clamp meter with a detachable wireless display that operates up to 30 ft from the measurement point. An included iFlex flexible current probe extends AC current range to 2500 A and reaches awkward or large conductors. CAT IV 600 V and CAT III 1000 V ratings cover industrial panels. Integrated low-pass filtering stabilises readings in electrically noisy environments.

Verify Jaw Access and Voltage Category Before Buying

Confirm the standard clamp jaw fits the conductors you typically measure; the iFlex probe is supplied for larger or hard-to-reach cables. Ensure the CAT IV 600 V / CAT III 1000 V rating matches the installation categories you work on. The wireless display requires line-of-sight within the stated distance, so check for obstructions or interference sources at the job site.

Detachable Display and Flexible Probe for Awkward

The display separates from the clamp body, letting you clamp the conductor then move to a safe or convenient position to read live values. iFlex coils around tight busbars or crowded cable trays where a rigid jaw cannot close. CAT IV 600 V / CAT III 1000 V housing and filtered signal processing withstand transient-rich switchgear. Wireless link maintains accuracy across the 30 ft range.

Questions about this item

Does the Fluke 381 come with the iFlex probe or must it be bought separately?

The Fluke 381 includes the iFlex flexible current probe in the box so no separate purchase is needed for that accessory.

How do the 381, 376, 375 and 374 models differ in features?

The 381 adds a detachable wireless display to the iFlex probe; the 376 includes iFlex but has a fixed display; the 375 and 374 are iFlex compatible but ship without the probe.

What does the 2500 A ac range mean when measuring with the iFlex?

With the iFlex probe attached the clamp meter can measure alternating current up to 2500 A on large or awkward conductors that do not fit the standard jaw.
