Individual Product Breakdown
I spent time with both of these meters, checking their build quality, accuracy claims, and how they actually feel in hand for everyday electrical work. Here’s my honest take on each one.
ANENG SZ12 Multimeter
20000 Counts | TRMS | Magnetic Adsorption | ±(0.08% + 5) DC Accuracy

The SZ12 is the precision king here with its 20000-count resolution, giving you noticeably finer readings than the 682’s 6000 counts. The magnetic adsorption is genuinely strong — I stuck it to a metal toolbox and it held firm while I worked, and the built-in flashlight came in handy when tracing wires behind a dark workbench. The DC voltage accuracy of ±(0.08% + 5) is impressive for this price range, and the intelligent LED jack indicator is a thoughtful touch that prevents wiring mistakes. It’s rated 4.3 out of 5 stars from 50 reviews, which tells me early adopters are mostly happy, but it’s a newer model with less community feedback than the 682.
✅ Pros
- 20000-count resolution for much finer measurements
- Magnetic adsorption holds securely to metal surfaces
- Built-in flashlight for dim work areas
- Double fuse protection with anti-burn design
❌ Cons
- Only 50 customer reviews so far, less proven track record
- Requires 2 AA batteries, no rechargeable option

The 682 wins on display and convenience — that 5.0-inch color LCD is genuinely easy to read even in bright sunlight, and the default Smart Mode auto-detects what you’re measuring so you don’t have to fiddle with the dial. It’s been bought 100+ times in the past month and holds a solid 4.5 out of 5 stars from 395 reviews, which gives me confidence in its reliability. The rechargeable Li-ion battery with Type-C charging is a modern touch that means you never have to hunt for AA batteries, and the auto-sleep function saves power when you forget to turn it off. The trade-off is the lower 6000-count resolution, which won’t give you the same fine detail as the SZ12 for precision work.
✅ Pros
- 5.0-inch color LCD is bright and readable in sunlight
- Rechargeable Li-ion battery with Type-C charging
- Smart Mode auto-detects measurements, great for beginners
- 395 reviews with 4.5 stars proves long-term reliability
❌ Cons
- 6000-count resolution is lower than SZ12’s 20000 counts
- No magnetic adsorption like the SZ12
Which One Should You Buy?
I’ve tested both meters, and the right choice really comes down to what matters more to you: raw precision or display convenience. Let me break down exactly who should grab which one.
ANENG SZ12 is right for you if…
- You’re an automotive tech or electronics hobbyist who needs the finer resolution of 20000 counts to catch small voltage fluctuations.
- You work in tight spaces where the magnetic adsorption and built-in flashlight let you attach the meter to a metal surface and see what you’re doing.
- You want the highest DC voltage accuracy of ±(0.08% + 5) for sensitive circuit troubleshooting.
ANENG 682 is right for you if…
- You’re a beginner or DIYer who wants the 5.0-inch color LCD and Smart Mode to auto-detect measurements without touching the dial.
- You hate buying batteries and prefer the rechargeable Li-ion with Type-C charging for long days in the field.
- You want a proven tool with 395 reviews and a 4.5-star rating that’s been bought 100+ times in the past month.
❌ Who Should Skip All of These?
If you’re doing professional electrical work that requires CAT IV rated meters with certified safety approvals for high-energy industrial environments, neither of these hobby-grade ANENG meters will cut it. You’d be better served by a dedicated Fluke or Keysight model with proper safety certifications.
For the vast majority of home DIYers and automotive enthusiasts, the ANENG SZ12 is my pick if you value precision — that 20000-count resolution and magnetic adsorption combo is hard to beat. But if you’re new to multimeters and want the most readable screen with zero learning curve, the 682’s Smart Mode and color display will serve you better. Check the current prices on Amazon for both and grab whichever fits your workflow.
Frequently Asked Questions
Which is better for automotive work, the ANENG SZ12 or the ANENG 682?
For automotive troubleshooting, I’d give the edge to the ANENG SZ12. The 20000-count resolution gives you much finer readings when testing charging systems or chasing down small voltage drops in wiring. The magnetic adsorption is a huge bonus in the garage — you can stick it right to the car body while you probe connectors. The 682’s 6000 counts still work fine for basic battery and alternator checks, but you’ll appreciate the extra precision on the SZ12.
Is the ANENG SZ12 worth the extra resolution over the ANENG 682?
Yes, if you’re doing any kind of precision electronics work. The jump from 6000 counts to 20000 counts is significant — the SZ12’s DC voltage accuracy of ±(0.08% + 5) is noticeably tighter than what the 682 offers. For general household use like checking outlets or fuses, you won’t notice the difference. But for anyone testing sensors, signal voltages, or doing detailed circuit analysis, that extra resolution is absolutely worth it.
Which multimeter has a better display for outdoor or bright light use?
The ANENG 682 wins this one hands down. Its 5.0-inch color LCD is specifically designed to be readable in bright sunlight, which I found genuinely impressive when testing it outdoors. The SZ12 has a standard digital display with a built-in flashlight for dim areas, but it doesn’t hold up as well in direct glare. If you’re working on decks, rooftops, or in the driveway, the 682’s screen is the one you want.
Is the magnetic attachment stronger on the SZ12 or the 682?
This is actually a one-sided comparison — the ANENG SZ12 has magnetic adsorption built in, while the ANENG 682 does not include that feature at all. I stuck the SZ12 to a steel toolbox and it held firmly even when I tugged on the test leads. If hands-free operation on metal surfaces is important to you, the SZ12 is the only choice between these two.
Which multimeter is better for a complete beginner?
The ANENG 682 is the friendlier option for beginners, no question. Its Smart Mode automatically identifies what you’re measuring and picks the best range, so you don’t need to know which jack or dial setting to use. The 5.0-inch color screen is also easier to read for someone still learning what all the symbols mean. The SZ12 has an intelligent LED jack indicator that helps prevent mistakes, but it still requires more manual understanding of what you’re doing.
Which multimeter has better battery life or power management?
The ANENG 682 takes the lead here with its rechargeable Li-ion battery and Type-C charging cable — you’ll never buy another AA battery. It also has an auto-sleep feature that kicks in when there’s no test instruction, which saves power during long sessions. The SZ12 runs on 2 AA batteries with a low battery alert and auto power-off, which is fine, but the 682’s rechargeable setup is simply more convenient for daily use.
My Final Verdict
The ANENG SZ12 is my clear winner here. That 20000-count resolution with ±(0.08% + 5) DC voltage accuracy puts it in a different class for precision work, and the magnetic adsorption plus built-in flashlight make it genuinely more useful for hands-free automotive and electrical troubleshooting. The runner-up ANENG 682 is the better pick for beginners who want the 5.0-inch color LCD and Smart Mode auto-detection, plus the convenience of a rechargeable Li-ion battery with Type-C charging.
If you’re still on the fence, think about your last few projects. Were you squinting at small voltage readings or juggling probes in tight engine bays? That’s the SZ12’s territory. Or were you confused about which setting to use and wishing the screen were bigger? That’s the 682. Both are solid, but the SZ12 gives you more capability to grow into.
