Fluke iFlex 2500A AC Current Probe

The Fluke iFlex 2500A is a flexible AC current probe designed for electricians and technicians measuring high current in tight spaces. It connects to compatible Fluke meters via the proprietary iFlex interface. The probe handles conductors up to 2.8 inches in diameter. It is built for professional test and measurement work.

Measurement Range and Safety Limits

This probe measures AC current from 0 A up to 2500 A with a flexible Rogowski coil design. It carries safety ratings of CAT III 1000V and CAT IV 600V for industrial environments. The maximum conductor size is 2.8 inches, setting a physical limit on cable bundles. No other measurement parameters are supported by this accessory.

Flexible Build and Daily Use

The flexible coil lets you wrap around large or awkward conductors where rigid jaws cannot fit. A 10-foot cable provides separation between the probe and the meter during live measurements. The iFlex connector locks onto the Fluke 381 for secure attachment. A three-year manufacturer warranty covers the probe.
