Measure current fast and accurately with Fluke amp clamps
Sparkies and HVAC techs know a reliable current reading can make or break diagnostics, and that's where a Fluke amp clamp earns its keep. These meters let you measure live circuits without breaking connections, giving you safe, fast readings on AC and DC current so you can troubleshoot panels, motors and control systems without downtime.
Whether you're running service calls, testing industrial equipment or sorting out a dodgy circuit, a Fluke clamp multimeter handles the job with accuracy you can count on. Models like the Fluke 324 and Fluke 323 deliver true RMS readings, letting you measure non-linear loads and variable frequency drives without second-guessing the numbers. For tighter spots or older gear, grab a clamp meter attachment that pairs with your existing multimeter and extends your measurement capability.
Tool Kit Depot stocks these meters across compact and full-feature models, so you've got the right tool whether you're doing light residential work or heavy industrial diagnostics. We've also got Fluke multimeters, insulation testers and voltage detectors to round out your electrical testing kit.

Fluke amp clamp FAQ
What is the difference between a clamp meter and a multimeter?
A clamp meter measures current by clamping around a conductor without breaking the circuit, while a standard multimeter requires you to connect test leads in series to measure current. The Fluke range gives you faster, safer current readings on live systems, making them ideal for high-current applications, motor testing and panel diagnostics. Multimeters excel at voltage, resistance and continuity checks where precision and flexibility matter more than speed.
What does RMS mean on a clamp meter?
RMS stands for root mean square, and a Fluke true RMS model measures the true effective value of AC current or voltage, even when the waveform isn't a perfect sine wave. This matters when you're testing variable speed drives, electronic ballasts or any equipment with distorted waveforms. Without true RMS, you'll get inaccurate readings that can throw off diagnostics and lead to the wrong call on repairs or replacements.
Can you measure DC current with a Fluke clamp meter?
Yes, but only if the model supports DC measurement. Many models are AC-only, so check the specs before you buy. If you need DC capability, look for models with Hall Effect sensors or consider a Fluke DC attachment that adds DC measurement to compatible multimeters. This is handy for automotive work, solar systems and battery testing where DC circuits are the norm.
How do I choose the right fluke clamp meter for my work?
Start by matching the meter's current range to the systems you test most often. Consider these factors:
Current range — residential circuits sit around 15–30 amps, industrial gear can run into hundreds
AC vs DC capability — sparkies mostly need AC, but auto and solar work demands DC
True RMS — essential for testing motors, drives and non-linear loads
Jaw opening size — bigger jaws handle large conductors or multiple cables at once
Models like the Fluke 324 and Fluke 323 cover most residential and light commercial work, while higher-end units add features like data logging, Bluetooth and expanded measurement functions.
Are these meters worth the investment?
Yes, if reliability and accuracy matter to your work. Fluke builds tough meters with accurate sensors, clear displays and solid warranties that hold up through daily site use. For sparkies doing diagnostic work where wrong readings cost time and money, it's a solid investment. You're paying for consistent performance, not just a name.
