Best Clamp Meters
Compare clamp meters by performance, capacity, accuracy, durability, compatibility, safety, and value to find the right option for your workshop.
Our shortlist
Fluke 376 FC is the first option we'd compare for professional high-current diagnostics. The alternatives intentionally cover different needs: Klein Tools CL800 for value electrician work, Hioki CM4373-50 for premium DC/AC current work, Amprobe AMP-320 for general HVAC/electrical. Choose by job fit first, then current price.
Quick comparison
| Model | Best for | Key configuration | Main drawback | Price |
|---|---|---|---|---|
| Fluke 376 FC | professional high-current diagnostics | true-RMS clamp meter compatible with flexible current probe | Confirm range, resolution/accuracy needs, calibration expectations and whether the tool is appropriate for the system or hazard being measured. | Price |
| Klein Tools CL800 | value electrician work | true-RMS AC/DC clamp meter with temperature and low-impedance mode | Confirm range, resolution/accuracy needs, calibration expectations and whether the tool is appropriate for the system or hazard being measured. | Price |
| Hioki CM4373-50 | premium DC/AC current work | rugged true-RMS clamp meter with DC current measurement | Confirm range, resolution/accuracy needs, calibration expectations and whether the tool is appropriate for the system or hazard being measured. | Price |
| Amprobe AMP-320 | general HVAC/electrical | true-RMS clamp meter with common troubleshooting functions | Confirm range, resolution/accuracy needs, calibration expectations and whether the tool is appropriate for the system or hazard being measured. | Price |
Fluke 376 FC
Key configuration: true-RMS clamp meter compatible with flexible current probe.
true-RMS clamp meter compatible with flexible current probe. Its value for professional high-current diagnostics comes from the measurement method, usable range and reading workflow rather than feature count alone.
Where it loses: Confirm range, resolution/accuracy needs, calibration expectations and whether the tool is appropriate for the system or hazard being measured.

Frequently asked questions
What safety rating should I look for in clamp meters?
Use a meter/tester with the measurement category, voltage rating and certifications appropriate to the electrical environment. The rating must cover the actual circuit being tested.
Does auto-ranging make a meter safer?
It can simplify operation, but it does not replace selecting the correct function, using intact rated leads and following safe electrical procedures.
True RMS or average responding?
True-RMS measurement is useful on non-sinusoidal loads such as variable-speed drives and many electronic power systems.
How often should test leads be inspected?
Before use. Replace leads with damaged insulation, loose probes or other defects and use only leads with appropriate ratings.
Can a non-contact voltage tester prove a circuit is de-energized?
Do not rely on a non-contact detector alone where formal verification of absence of voltage is required. Follow the applicable safe-work procedure and test-instrument method.
What does CAT III versus CAT IV mean?
Measurement categories relate to where transient energy can occur in an electrical installation. Higher category is not simply 'more accurate'; select equipment appropriate to the location.
When should a meter be calibrated?
Follow the maker's calibration interval and any quality-system requirements. Calibration matters most when measurements must be traceable or accuracy is critical.
