This uniquely-designed clamp meter includes all of the functionality you'd expect of a normal clamp meter, but also comes with the ability to remove the tester's display and view it safely from a distance!
The display uses wirelessly technology to interface directly with the clamp. It can be used up to a distance of 30ft away from the measurement point and is even fully magnetic for mounting on an easy-to-see surface!
Measuring in difficult applications where your standard clamp meter won't fit? The 381 is also supplied as standard with a flexible current probe that can easily be bent around a difficult area and can measure up to 2500A AC.
