If you’re hunting for a pen-style multimeter, the ANENG A3009 and ANENG SZ301 are two names that keep popping up. The A3009 is the higher-spec model with a 6000-count display and phase sequence detection, while the SZ301 is a simpler, more affordable option that still covers AC/DC voltage, current, resistance, and capacitance.
I’ve spent time with both of these to figure out which one actually makes sense for your toolbox. The real question is whether you need the A3009’s extra sensitivity and features, or if the SZ301’s straightforward design and included case are enough for your projects. Let’s break it down so you can buy with confidence.

Individual Product Breakdown
I tested both of these pen-style multimeters side by side, checking accuracy, build quality, and how comfortable they are to use in tight spots. Here’s what I found with each one.

The A3009 is the more feature-packed of the two, and I really appreciate the 6000-count display for getting finer readings on sensitive electronics. The phase sequence detection is a standout — it’s not something you see on most pen testers in this category, and it makes troubleshooting three-phase systems much easier. I also like the auto-ranging and the fact that it automatically identifies the measurement parameter, which speeds things up when I’m switching between tasks. My only gripe is that it uses AAA batteries instead of the AAs in the SZ301, so battery life feels a bit shorter in practice.
✅ Pros
- 6000-count display for higher resolution readings
- Phase sequence detection — rare in pen testers
- Auto-ranging and auto parameter detection
- Includes flashlight and backlit screen for dark work
❌ Cons
- Uses AAA batteries — shorter runtime than AA
- No included case for storage

The SZ301 is the practical budget pick, and honestly, it surprised me with how much it packs in for the price. The 10A current range is a big deal — it’s double what the A3009 can handle, making it better for automotive and appliance work. I appreciate the included silicone protective case and the fact that it runs on two AA batteries, which are pre-installed. The display is clear and easy to read, though the resolution tops out lower than the A3009, so it’s not ideal for super-precise electronics work.
✅ Pros
- 10A current range for automotive and appliance testing
- Includes silicone protective case and test leads
- Runs on AA batteries with pre-installed pair
- Double fuse anti-burn protection for safety
❌ Cons
- Lower resolution than the A3009 for fine measurements
- No phase sequence detection feature
Which One Should You Buy?
After spending time with both, I can tell you there’s no single “right” answer — it really comes down to what you’re measuring and how often. Let me match each meter to the person who’d get the most out of it.
ANENG A3009 is right for you if…
- You work on three-phase electrical systems and need the phase sequence detection feature
- You’re troubleshooting sensitive electronics that demand the finer 6000-count resolution
- You often work in dark spaces and rely on the built-in flashlight and backlit screen
ANENG SZ301 is right for you if…
- You work on cars or appliances where the 10A current range is essential for testing circuits
- You want a ready-to-go kit with a silicone case, test leads, and pre-installed AA batteries
- You’re a hobbyist or student who needs a solid all-rounder without spending extra
❌ Who Should Skip All of These?
If you’re a professional electrician doing high-voltage work daily, or you need data logging and Bluetooth connectivity, skip both of these. You’ll want a full-size bench meter or a smart clamp meter with more advanced safety certifications.
For most DIYers and home users, I’d lean toward the ANENG SZ301 — the 10A current range and included case make it the better value for everyday tasks. But if you’re already comfortable with pen testers and need that extra resolution for electronics, the A3009 is worth the step up.
Frequently Asked Questions
Which is better for automotive work, the ANENG A3009 or the ANENG SZ301?
Go with the ANENG SZ301 for car repairs. It handles up to 10A of current, which is essential for testing starter circuits, alternators, and parasitic draws — the A3009 doesn’t match that current range. The SZ301 also comes with a silicone case, which is nice when you’re working in a messy engine bay.
Is the ANENG A3009 worth the extra money over the SZ301?
Only if you need the finer 6000-count resolution or the phase sequence detection. For most home and hobby use, the SZ301 gives you 90% of the functionality at a lower price. But if you’re troubleshooting sensitive electronics or three-phase systems, the A3009’s extra features justify the cost.
Do both multimeters have non-contact voltage detection?
Yes, both the A3009 and SZ301 include NCV (non-contact voltage) testing. The A3009 pairs it with auto-ranging and automatic parameter detection, so it takes a bit more guesswork out of the measurement. The SZ301 keeps things simpler but still gets the job done for live wire detection.
Which pen multimeter is easier to carry around?
Both are compact pen-style meters, but the SZ301 is the more portable package overall. It includes a silicone protective case and runs on two AA batteries, which are easier to find on the go. The A3009 is slightly lighter at 6.3 ounces, but it uses AAA batteries and doesn’t include a case.
Can the ANENG A3009 measure capacitance?
Yes, the A3009 measures capacitance along with AC/DC voltage, current, resistance, continuity, and diodes. The SZ301 also covers capacitance, but the A3009’s 6000-count display gives you more precise readings on smaller capacitor values, which I found helpful when testing circuit boards.
Which is better for a beginner just learning electronics?
Start with the ANENG SZ301. It’s more affordable, includes a protective case, and the simpler interface is easier to wrap your head around when you’re first starting out. The A3009’s auto-ranging and extra features are nice, but they can feel overwhelming if you’re just learning the basics of voltage and resistance testing.
My Final Verdict
The ANENG A3009 takes the win for me. Its 6000-count display and phase sequence detection put it in a different league for anyone doing serious electrical troubleshooting, and the auto-ranging makes it faster to use in the field. The ANENG SZ301 is the runner-up, and it’s the better pick if you need the 10A current range for automotive work or just want a budget-friendly option with a case included.
If you’re still on the fence, think about what you’ll actually measure most. If it’s car batteries and appliance circuits, the SZ301’s higher current range wins. If it’s electronics or three-phase systems, the A3009’s resolution and phase detection are worth the extra investment.
