When it comes to choosing the right Fluke clamp meter, entry-level electricians and experienced professionals alike need to consider factors like accuracy, measurement capabilities, and safety ratings. Three excellent options under $200, each best suited for different applications, include:
Here’s how they compare.
Comparing Key Differences at a Glance
The Fluke 323 and Fluke 302+ are both capable clamp meters for basic current and voltage testing. However, the 323 offers true-RMS accuracy, making it the better choice for working with fluctuating loads.
The Fluke 301D, on the other hand, stands out with a higher 600A current range (the 323 and 302+ go up to 400A). It also features a backlit display and a CAT IV safety rating, making it more versatile for industrial settings.

Which Clamp Meter Should You Choose?
Your ideal clamp meter depends on your application, budget, and accuracy requirements. Consider the following to decide which tool best suits your needs:
- Fluke 323: Best for HVAC and general electrical work where true-RMS accuracy is necessary for measuring non-linear loads. Go check it out.
- Fluke 302+: A budget-friendly option for basic electrical testing and maintenance, but lacks true-RMS. You need this in your toolkit.
- Fluke 301D: The most versatile choice, offering higher current capacity (600A), CAT IV safety rating, frequency measurement, and a backlit display — ideal for industrial and commercial environments. See what all the fuss is about.
If accuracy is your priority, go for the Fluke 323. If you need a compact and affordable option, the Fluke 302+ is a solid pick. But if you want higher amperage, better safety ratings, and more advanced features, the Fluke 301D is worth the extra investment.
