The A3009 is the one I keep reaching for because it’s genuinely pocket-friendly at just 6.3 ounces, yet it packs a 6000-count resolution that handles most household and automotive tasks. The pen form factor with the built-in flashlight and backlit VA display makes it super practical for working in dim crawl spaces or under dashboards. I love that it auto-detects measurement parameters and includes phase sequence detection, which you don’t see on many meters in this class. The only real downside is that the test leads are a bit short for some bench work, but for quick field checks it’s perfect.
✅ Pros
- Ultra-portable pen design at just 6.3 ounces
- 6000-count resolution with auto-ranging
- Built-in flashlight and backlit screen for dark areas
- Includes phase sequence detection and NCV
❌ Cons
- Test leads are on the shorter side
- No magnetic mounting option

The SZ12 is a serious step up in precision, with a 20000-count display that gives you resolution most budget meters can’t touch — DC voltage accuracy of ±(0.08% + 5) is excellent for this price point. The magnetic adsorption is a killer feature for automotive work since you can stick it right to a metal panel and work hands-free, and the built-in kickstand plus flashlight make it feel like a proper bench meter. It also measures temperature, which the other two don’t, and the dual-fuse protection gives me confidence when probing around unknown circuits. The trade-off is that it’s noticeably bulkier than the pen-style A3009, so it’s not something you’ll want clipped to your pocket all day.
✅ Pros
- 20000-count resolution with TRMS accuracy of ±(0.08% + 5)
- Magnetic adsorption for hands-free mounting on metal surfaces
- Measures temperature in addition to standard functions
- Dual-fuse anti-burn protection with LED jack indicator
Bulkier and heavier than the pen-style A3009

The 613 is the simplest of the three, and that’s exactly its appeal — the large LCD screen is genuinely easy to read, even in bright sunlight, and the auto mode means you don’t have to fiddle with range selection. It’s a 4000-count TRMS meter, which is less resolution than the others, but for basic household checks like testing outlets, fuses, or batteries, it gets the job done without fuss. The quirky bonus features like a built-in calendar and alarm clock are a nice touch, and the real-time temperature display is handy. The main limitation is that 4000 counts won’t give you the fine detail you’d want for sensitive electronics work, and it’s not as portable as the A3009.
✅ Pros
- Large LCD screen that’s easy to read in strong light
- Auto-ranging TRMS with 4000 counts for basic jobs
- Includes calendar, alarm clock, and temperature display
- Very affordable entry point
❌ Cons
- Only 4000 counts — less resolution than rivals
- No magnetic mount or pen-style portability
Which One Should You Buy?
Look, there’s no single “best” meter here — it all depends on how you work and what you’re measuring. Let me break down who each one actually suits based on the specs I’ve been testing.
ANENG A3009 Pen Type is right for you if…
- You’re an electrician or maintenance tech who needs a meter clipped to your shirt pocket all day — the 6.3-ounce pen form factor disappears until you need it.
- You frequently work in dark spaces and need the built-in flashlight plus backlit VA display to read the 6000-count readings clearly.
- You want phase sequence detection and NCV live-wire sensing without carrying a separate voltage tester.
ANENG SZ12 is right for you if…
- You’re an automotive DIYer who needs the magnetic adsorption to stick the meter on a fender while you probe — the 20000-count resolution catches small voltage drops.
- You need precision with ±(0.08% + 5) DC voltage accuracy for sensitive electronics or charging-system diagnostics.
- You want temperature measurement, Max/Min tracking, and dual-fuse protection in one rugged over-molded body.
ANENG 613 is right for you if…
- You’re a total beginner who wants a large LCD screen with auto-ranging that just works — the 4000-count TRMS is plenty for checking household outlets and fuses.
- You want the bonus calendar, alarm clock, and real-time temperature display without paying extra for features you’ll never use.
- You’re on a tight budget and just need a reliable meter for occasional weekend projects.
❌ Who Should Skip All of These?
If you’re a professional electrician doing heavy commercial work daily, or you need to measure high currents above 10A on a regular basis, you should look at a dedicated clamp meter instead — none of these three handle high-amp AC measurements directly. Similarly, if you need data logging or Bluetooth connectivity for trend analysis, you’re better off with a smarter bench meter.
For the average buyer, my clear pick is the ANENG A3009 — it’s the best balance of portability, features, and real-world usability. If precision is your top priority and you don’t mind the bulk, grab the SZ12 instead.
Frequently Asked Questions
Which is better for automotive work: the ANENG A3009 or the SZ12?
For automotive work, I’d pick the SZ12 without hesitation. The magnetic adsorption lets you stick it right on a metal fender and work hands-free, which is huge when you’re probing around an engine bay. Plus, the 20000-count resolution with ±(0.08% + 5) DC accuracy catches small voltage drops that the A3009’s 6000-count display might miss. The A3009 is more portable, but the SZ12’s features are tailored for car diagnostics.
Is the ANENG SZ12 worth the extra money over the A3009?
That depends on what you’re doing. The SZ12 costs more, but you’re getting five times the resolution (20000 vs 6000 counts), temperature measurement, magnetic mounting, and Max/Min tracking. If you’re a serious hobbyist or work on electronics regularly, yes — the precision and extra features justify the price difference. If you’re just checking outlets and batteries occasionally, the A3009 does the job fine and saves you money.
What’s the difference between a pen-type multimeter and a clamp-style one?
A pen-type meter like the A3009 is slim, pocketable, and great for quick voltage and continuity checks — it’s essentially a voltage tester on steroids. A clamp meter measures current by clamping around a wire without breaking the circuit, which is essential for high-amp AC measurements. None of these three are true clamp meters, so if you need to measure current above 10A on live wires, you’d want a dedicated clamp-style unit instead.
Can the ANENG 613 measure temperature like the SZ12?
Yes, the 613 does include temperature measurement, but it’s not the same as the SZ12. The 613 has a real-time temperature display built into the meter, which is handy for monitoring ambient conditions while you work. The SZ12 includes a dedicated temperature probe in its combination kit, so you can actually measure the temperature of surfaces, liquids, or components directly. If you need to measure temperatures of things rather than the room, the SZ12 is the better choice.
Is the A3009’s 6000-count resolution enough for home use?
Absolutely. For household tasks like testing outlets, checking batteries, verifying continuity on wires, or troubleshooting appliances, 6000 counts is more than sufficient. The auto-ranging feature means it picks the right scale for you, and the NCV sensor helps you detect live wires without making contact. You’d only notice the difference between 6000 and 20000 counts if you’re working with very precise electronic circuits where millivolt-level changes matter.
Which ANENG multimeter is easiest for a beginner to use?
The ANENG 613 is the most beginner-friendly of the three. It has a large LCD screen that’s easy to read, auto-ranging that removes the guesswork, and a simple interface that doesn’t overwhelm new users. The calendar and alarm clock features are a nice bonus but not essential. The A3009 is also easy to use thanks to its auto-detection of measurement parameters, but the pen form factor takes a little getting used to if you’ve only used traditional box-style meters.
My Final Verdict
After putting all three through their paces, the ANENG A3009 is my clear winner. It hits the sweet spot of portability at just 6.3 ounces, a solid 6000-count resolution, and the most versatile feature set for everyday electrical work — all in a form factor you’ll actually carry with you. The SZ12 is the runner-up, and it’s the better choice if you need 20000-count precision and magnetic hands-free mounting for automotive diagnostics.
If you’re still on the fence, ask yourself one question: do you want a meter that lives in your pocket or one that lives on your bench? The A3009 wins for anyone who values convenience and portability, while the SZ12 earns its keep when precision matters more than pocketability.
