FLUKE 323 True RMS Clamp Meter: Dependable, Accurate, and Built to Last
The FLUKE 323 True RMS Clamp Meter is the essential tool for electricians and technicians who demand reliable, accurate results without complication. Designed specifically for general electrical troubleshooting, this meter is perfect for daily use in both residential and commercial environments.
When you‘re checking current in a tight space or verifying voltage safely on the go, the FLUKE 323 delivers consistent, noise-free readings. It‘s built tough for demanding work environments, providing the reliability you need to confidently diagnose electrical issues.

Why The FLUKE 323 Stands Out
For professionals needing a dependable tool that performs consistently, the FLUKE 323 excels. Its slim, ergonomic design fits comfortably in your hand and easily navigates cramped electrical panels and tightly packed wires. The rugged construction and renowned FLUKE reliability mean it‘s ready for any job site, boasting an IP30 rating for protection against solid objects larger than 2.5mm, ensuring its durability.
The FLUKE 323 clamp meter measures AC current up to 400 amps, along with AC and DC voltage up to 600 volts. It also efficiently checks for continuity in circuits, switches, fuses, and contacts – all crucial for daily fault-finding tasks.
Accurate Readings You Can Trust
Equipped with True RMS technology, the FLUKE 323 provides precise readings even on non-linear loads like variable-speed drives or electronic ballasts. Where other meters might deliver misleading values, this model ensures accuracy. Please note that while its large display is clear and easy to read, the FLUKE 323 does not feature a backlit display.
Whether you‘re an apprentice, a maintenance engineer, or an experienced technician, the FLUKE 323 offers dependable performance and quick measurements every time.
