Agilent/Keysight U1211A Clamp Meter 1000A

The Keysight U1211A is a handheld clamp meter designed for a variety of electrical measurements, with a focus on high-current applications. It has a 3.5-digit resolution and includes features such as True RMS AC measurements, a built-in LED flashlight, and a large clamp jaw opening suitable for thick cables. This instrument is intended for troubleshooting and general-purpose electrical testing in industrial and field environments. the U1211A model has been discontinued and marked as obsolete.
