Agilent U1240 Series Handheld

Digital Multimeters

Helping You Check and Fix More Installation

and Maintenance Bugs

Data Sheet

The Agilent U1240 Series handheld digital multimeters enable you to check

more with wider measurement ranges. They feature true RMS readings on their

10,000-count displays. The adjustable backlighting allows you to complete your

jobs even in subdued lighting conditions, or to simply prolong battery life. Your

maintenance tasks are greatly simplified due to the built-in switch counter,

harmonic ratio, dual and differential temperature capabilities, with just a press

of the button. The meters have a high safety rating with CAT III 1000 V and

CATIV600 V protection and are certified to CE and CSA standards. On top of

that, the U1240 Series comes with a certificate of calibration and test report –

at no extra cost.

The latest multimeters in this series, the U1241B and U1242B, now come in

vivid orange cases, offering the capabilities and functions you need.
