Agilent U1731B Data Sheet

Agilent U1700 Series handheld LCR meters expand Agilent’s portfolio of handheld tools into electronics assembly and passive components troubleshooting. Better yet, these handheld models extends the tradition of Agilent’s industry-leading benchtop units to more affordable and portable forms. Agilent’s latest handheld LCR meters in all-new orange offer capabilities and functionalities equivalent to the A models.

Agilent U1700 Series Handheld LCR Meters

Data Sheet

Test passive components conveniently, affordably and reliably with the Agilent U1700 Series LCR meters — extending the tradition of industry-leading benchtop units

No waiting for quick, basic LCR tests

Sharing a bench LCR meter is practical, but isn’t always convenient. With Agilent’s new line of handheld LCR meters, you can perform quick, basic LCR measurements at your convenience. Now that they’re available at a lower price point compared to traditional benchtop units, everyone on your team can be equipped for passive-component testing— on the bench or on the go—without the wait.

Uncompromised quality and reliability

The handheld LCR meters are housed in robust overmold and tested to stringent industrial standards. Each LCR meter is also sealed with a three-year warranty and the assurance that you can test your components with confidence.
