Sharing a bench LCR meter is practical, but isn’t always convenient. With Keysight’s new line of handheld LCR meters, you can perform quick, basic LCR measurements at your convenience. Better yet, our handheld models extend the tradition of our industry-leading benchtop units to a lower price point. Now, everyone on your team can be equipped for passive-component testing—on the bench or on the go—without the wait.

The U1731B is now available, with the same outstanding performance and reliability of the U1731A, but in bright orange casing. Designed to give maximum visibility, the vivid color underlines Keysight commitment to safety in each of its handhelds.
