Heavy Duty, Autoranging Digital Multimeter

The Extech EX505 was designed specifically for industrial, plant maintenance, MRO, electrical and other professionals who need a heavy-duty, feature-rich multimeter.

Functional Overview

The EX505 is a True RMS digital multimeter capable of taking numerous measurements, including capacitance, frequency (dual sensitivity for electrical and electronic applications), diode test and continuity. Other features include Data Hold and Relative Hold, and auto-ranging, which automatically adjusts the measurement range based on the detected source, such as electrical components and electronic equipment.

True RMS Capable

It can be very difficult to make accurate current and voltage readings in industrial and commercial environments where electronic devices are present. Fluorescent lights, motor drives, computer power supplies, and other electronic components can distort the AC waveform, making it hard for averaging meters to get an accurate reading. The EX505 uses a more advanced True RMS calculation to compensate for this kind of distortion.

Rugged & Versatile

Designed to withstand harsh environments and usage, the EX505’s rugged, double-molded housing is IP67-rated (waterproof and dustproof) as well as drop-tested to 6 feet. The large, illuminated LCD displays a 4-digit readout (to 4,000 counts). The meter features 0.5% accuracy and a CAT IV-600V safety rating, protecting users even on outdoor wiring.

Marine-Ready

As a waterproof tool, the EX505 has become a popular multimeter among marine technicians and boat mechanics who risk dropping the meter off a boat, pier or dock and into water. Since the meter is waterproof and floats, it’s easy to recover and is ready to resume work once retrieved. The EX505 features Auto Power Off (with disable) to conserve battery life, and the meter is backed by a three-year limited warranty.
