Price Match Guarantee & Advice

Small in size for those difficult applications such as testing inside engines, the Extech MA140 is a true RMS, AC only clamp meter ideal for quick and easy measurements.

The meter features 0.8" (22mm) jaw sizes and accommodates conductors up to 300MCM. The tester's slim body ensures it doesn't get in the way when testing, making it much more suitable for tight measurements than other, larger clamp meters.

The MA140 can measure AC current across two ranges up to a maximum of 300A with basic accuracy of ±2.0%. An inrush current function and a built-in non contact voltage detector are also included.

This clamp meter's unique Smart data hold function uses audio and visual alerts to inform the user when a new reading is more than 50 digits of the current held reading, making it easier to track irregularities.
