10 Best Volt Meters 2025 in the United States

The Fluke 323 Clamp Meter is a reliable tool designed for both commercial and residential electricians. It measures AC current up to 400 amps and AC/DC voltage up to 600 volts, making it versatile for various electrical tasks. One of its major strengths is the True RMS sensing feature, ensuring accurate readings for both linear and non-linear loads. The meter also measures resistance up to 4 kilo ohms and offers an audible continuity sensor, which helps confirm if a circuit is conducting electricity.

Additionally, it meets stringent IEC safety standards and is rated for CAT IV installations up to 300V and CAT III installations up to 600V, indicating high safety levels for professional use. The jaw opening can measure current in a conductor up to 30 mm without interrupting the circuit, enhancing its convenience and safety further. The device is lightweight at 200 grams and comes with a soft carrying case and a 2-year warranty, adding to its portability and reliability.

However, it does not measure DC current, which might limit its use for some specific applications. Also, being a corded electric device powered by two AAA batteries, it might require regular battery replacements. Despite these minor drawbacks, the Fluke 323 Clamp Meter stands out for its high accuracy, robust build, and essential features, making it a strong choice for professional electricians.
