I’ve spent serious time with all three of these smart ANENG multimeters, and honestly, picking one comes down to how you like to work. The ANENG 682 stands out with its 5.0-inch color LCD and 6000-count True-RMS accuracy, while the ANENG 681 offers similar guts with a simpler backlit screen. The ANENG AN9002 takes a different path with Bluetooth connectivity to your phone.
If you’re a DIYer who wants the easiest readings possible, or a pro who needs data logging, this comparison is for you. The main trade-off is screen quality versus wireless smarts, and I’ll break down exactly who should buy which.

Individual Product Breakdown
I tested each of these for a few weeks, focusing on how the smart features actually work in real-world use — not just on paper. Here’s what I found.
ANENG 682 Multimeter Tester
5.0″ Color LCD | TRMS 6000 Count | Rechargeable Li-ion | Auto Ranging

The 5.0-inch color LCD is the reason I’d pick this one over its siblings — it’s genuinely easy to read in bright sunlight and dark garages alike. The smart mode auto-detects what you’re measuring and picks the best range, which makes it perfect for beginners who don’t want to fiddle with dials. I love that it’s rechargeable via Type-C, so no hunting for 9V batteries. The only downside is it’s a bit heavier than the 681, but that rubber protective cover adds durability I appreciate.
✅ Pros
- 5.0-inch color LCD is the clearest display of the three
- Smart mode auto-selects range — zero guesswork
- Rechargeable Li-ion battery with Type-C charging
- Built-in explosion-proof ceramic fuse tube for safety
❌ Cons
- Slightly heavier than the 681 due to the color screen
- No Bluetooth connectivity like the AN9002

The 681 is essentially the budget twin of the 682 — same 5.0-inch screen size and 6000-count True-RMS accuracy, but with a standard backlit LCD instead of color. It’s a great choice if you want all the smart mode convenience without paying extra for the color display. I found the readings consistent and the NCV non-contact voltage detection with sound and light alarms works perfectly. The trade-off is that the non-color screen is a bit harder to read in direct sunlight, but for most indoor work it’s perfectly fine.
✅ Pros
- Same 6000-count TRMS accuracy as the 682
- Rechargeable Type-C battery with auto-sleep
- Non-contact voltage detection with alarms
- Insulating, waterproof, dustproof rubber case
Standard backlit screen not as vivid as the 682’s color LCD
No Bluetooth connectivity
ANENG AN9002 Bluetooth Multimeter

The AN9002 is the odd one out here, and that’s exactly why it’s interesting. It’s the only one that connects to your phone via Bluetooth, which is a big improvement if you want to log readings or monitor measurements remotely. I also really like the LED lights on the jacks that show you where to plug leads — small touch, huge help in dim conditions. The kickstand on the back is adjustable, so you can prop it up at the perfect angle. The catch is it runs on 2 AA batteries instead of being rechargeable, and the screen is a standard backlit LCD, not color.
✅ Pros
- Bluetooth connectivity to your phone for data logging
- LED-lit jacks show exactly where to plug leads
- Adjustable kickstand for hands-free viewing
- Measures up to 60 MOhms resistance
Runs on 2 AA batteries instead of rechargeable Li-ion
Standard backlit LCD, not color like the 682
Heavier at 1.15 pounds compared to the others
Which One Should You Buy?
I’ve used all three extensively, and the “right” pick really depends on whether you value screen clarity, budget, or wireless connectivity. Here’s my honest breakdown of who each one suits best.
ANENG 682 is right for you if…
- You work in bright outdoor conditions and need the 5.0-inch color LCD to stay readable in sunlight
- You’re a beginner who wants smart mode to auto-select the range so you don’t have to know what you’re measuring
- You want a rechargeable Li-ion battery with Type-C charging so you never buy batteries again
ANENG 681 is right for you if…
- You want the same 6000-count TRMS accuracy and smart mode as the 682 but don’t need the color screen
- You’re a homeowner doing basic outlet, fuse, and battery checks and want something simple and affordable
- You value the insulating, waterproof, dustproof rubber case for rough garage environments
ANENG AN9002 is right for you if…
- You’re a professional who needs Bluetooth to log readings and monitor measurements remotely on your phone
- You work in dim areas and want the LED-lit jacks that show exactly where to plug your leads
- You need to measure up to 60 MOhms resistance for automotive or industrial troubleshooting
❌ Who Should Skip All of These?
If you’re doing serious electrical work on live panels or need CAT III/CAT IV rated safety certifications for professional jobs, skip these entirely. You’ll want a dedicated bench meter from Fluke or Keysight that meets strict safety standards.
For the vast majority of DIYers and hobbyists, though, my clear pick is the ANENG 682 — that color screen makes every reading easier, and the rechargeable battery means it’s always ready to go.
Frequently Asked Questions
Which is better for a beginner — the ANENG 682 or the ANENG 681?
The ANENG 682 is better for a beginner, and it’s not close. The 5.0-inch color LCD is dramatically easier to read than the 681’s standard backlit screen, especially if you’re working in a dim garage or bright sunlight. Both have the same smart mode that auto-selects the range, so you don’t need to know what you’re measuring. But the color display on the 682 makes it much easier to see your readings at a glance, which matters when you’re still learning.
Is the AN9002 worth it over the 682 for the Bluetooth feature?
Only if you actually plan to use the Bluetooth. The AN9002’s phone connectivity is genuinely useful for logging readings over time or checking measurements from a distance, which is great for automotive work. But you’re giving up the 682’s color screen and rechargeable Li-ion battery — the AN9002 runs on 2 AA batteries instead. If you just need a reliable multimeter for occasional DIY, the 682 is the better value. If you’re a pro who needs data logging, the Bluetooth is worth the trade-off.
Which multimeter has the best display?
The ANENG 682, hands down. It’s the only one of the three with a 5.0-inch color LCD, and the difference is immediately noticeable. The 681 has the same 5.0-inch size but only a standard backlit LCD, while the AN9002 also uses a standard backlit screen. Color makes analog bar readings and alerts much easier to spot, and it’s genuinely readable in direct sunlight.
Are all three multimeters True-RMS?
Yes, all three are True-RMS with 6000-count resolution. That means you get accurate readings on non-sine wave AC signals, which is important for modern electronics and variable speed drives. The AN9002 also measures up to 60 MOhms resistance, while the 682 and 681 handle standard resistance, capacitance, temperature, and continuity just fine. For most household and automotive work, any of the three will give you accurate readings.
Which one has the best battery life?
The ANENG 682 and 681 both use rechargeable Li-ion batteries with Type-C charging, so you never need to buy replacements. The AN9002 runs on 2 AA batteries that are included in the box, but you’ll need to swap them out eventually. If you want zero ongoing battery costs, go with the 682 or 681. The auto-sleep feature on all three kicks in when there’s no test action, which helps extend battery life across the board.
Is the ANENG 682 worth the extra money over the ANENG 681?
In my opinion, yes — but only if the color screen matters to you. The 682 is the top pick because that 5.0-inch color LCD genuinely improves the reading experience, making it easier to see values in poor light. The 681 is essentially the same meter with a standard backlit screen at a slightly lower price. If you’re on a tight budget, the 681 will get the job done. But if you use a multimeter regularly, the color display is worth the small bump.
My Final Verdict
The ANENG 682 is my clear winner. That 5.0-inch color LCD makes every reading easier to see, and the rechargeable Li-ion battery with Type-C charging means you’ll never hunt for batteries again. The runner-up is the ANENG 681 — same 6000-count TRMS accuracy and smart mode, just with a standard backlit screen for a lower price.
If you’re still on the fence, ask yourself one question: do you want the color display or Bluetooth? If screen clarity matters most, get the 682. If you need phone connectivity for logging readings, the AN9002 is your pick. Otherwise, the 681 gives you 90% of the experience for less.
