Fluke 381 Remote Display TRMS Clamp Meter

Introduction:

The Fluke 381 is a handheld, battery-operated Clamp Meter (the Meter) that has a remote-display module and detachable iFlex (Flexible Current Probe). The Remote Display can be removed from the Meter body and read away from the measurement source. This lets the display be easily read in difficult-measurement situations such as a hazardous environments, or very tight spaces. The Flexible Current Probe makes it possible to measure higher current (up to 2500 A ac) and larger cables that traditional jawed meters cannot measure.
