Extech 381676A Pen Digital Multimeter with NCV

The Extech 381676A is a 9-function pen-style digital multimeter with a built-in non-contact voltage (NCV) detector, purpose-built for technicians who need a full-featured meter in a slim, pocket-sized form factor. With a 2000-count LCD and auto/manual ranging, it covers AC/DC voltage up to 600V, DC current to 200mA, resistance to 20MΩ, logic test, diode test, and continuity, all from a pen multimeter compact enough to clip into a shirt pocket or tool pouch. Its CAT III-600V safety rating ensures it is qualified for professional use on aircraft electrical panels, avionics wiring, and MRO workbench diagnostics.

Key Features

• 9 measurement functions including AC/DC voltage, DC current, resistance, logic test, diode, and continuity
• Built-in non-contact AC voltage (NCV) detector with audible and visual alert for rapid live-wire identification
• 2000-count high-contrast LCD display for clear readings in tight spaces

Applications

The 381676A pen multimeter is a go-to diagnostic tool for A&P mechanics and avionics technicians who perform line maintenance, pre-flight electrical checks, and circuit continuity tests on commercial and general aviation aircraft. Its slim pen-style design allows easy access to tight aircraft wiring bays and avionics racks where a standard multimeter would be difficult to maneuver. The NCV function provides a fast, contact-free method for identifying live conductors in aircraft electrical systems, a critical safety step before any wiring work in MRO and hangar environments.
