描述

Whether you need to quickly inspect power supplies for harmonics, detect glitches in switch systems or monitor differential temperature, the U1240 Series handheld digital multimeters (DMMs) are up to the task.

Keysight’s range of handheld test tools includes safety features that help you perform day-to-day measurements with confidence. Reduce the risk of injury due to arc flash while probing near-contact points with specially designed 4-mm-tip probes. A built-in 30 kA high-energy fuse shields you from potentially violent fuse failures when working in high-current environments.

Our latest handheld DMMs in bright orange cases are a vivid reminder that you have an extra layer of protection between you and the unknown.
