The AstroAI DM200M is the clear winner if you actually need accurate readings for anything beyond basic checks. I love the True RMS feature — it makes a real difference when measuring non-sine wave AC signals, and the NCV detector is handy for finding live wires without touching them. The CAT III 600V safety rating and ceramic fuses give me confidence when working around household circuits. My only gripe is the size is a bit bulky compared to the Assark, but the extra features are worth the trade-off.
✅ Pros
- True RMS delivers accurate AC readings
- CAT III 600V safety with ceramic fuses
- NCV detection for live wires
- 800+ bought in past month — proven popularity
❌ Cons
- Larger than pocket meters — not as portable
- No built-in battery check function

The Assark 2000 Counts is the cheapest option I tested, and for basic voltage checks and continuity tests, it gets the job done. I really appreciate how tiny it is — at just 0.18 pounds and 3.94 x 1.97 x 1.1 inches, it disappears in a pocket. The battery check mode for 1.5V and 9V batteries is a nice bonus that the AstroAI doesn’t have. But you give up a lot: no True RMS, no NCV, and it can’t measure AC current at all, so it’s strictly for light DIY work.
✅ Pros
- Ultra-portable pocket size at 0.18 lbs
- Built-in battery check for 1.5V and 9V
- Backlit LCD for dim areas
- 300+ bought in past month — budget favorite
❌ Cons
- No True RMS — less accurate on non-sine waves
- Cannot measure AC current at all
- No NCV or CAT III safety rating
Which One Should You Buy?
I’ve tested both meters thoroughly, and the right choice really comes down to what kind of electrical work you actually do. Let me break down who each one fits best.
AstroAI Digital Multimeter (DM200M) is right for you if…
- You need True RMS accuracy for measuring non-sine wave AC signals in appliances or electronics
- You work around live circuits and want CAT III 600V safety with ceramic fuses for protection
- You want NCV detection to quickly find live wires without touching them during troubleshooting
Assark Digital Multimeter (620A) is right for you if…
- You need a tiny meter that fits in your pocket at just 0.18 pounds for quick on-the-go checks
- You only need basic DC voltage and continuity tests for automotive or simple battery work
- You want a built-in battery check for 1.5V and 9V batteries without needing a separate tester
❌ Who Should Skip All of These?
If you’re a professional electrician working with high-power circuits daily, skip both of these. You’ll want a meter with a higher safety rating like CAT IV and more measurement ranges — these budget units are for hobbyists and homeowners.
For most people, I’d grab the AstroAI DM200M. The True RMS accuracy and CAT III safety make it worth the extra cost, and you’ll use it for years without outgrowing it.
Frequently Asked Questions
Which is better for a beginner, the AstroAI DM200M or the Assark 2000 Counts?
I’d point a beginner toward the AstroAI DM200M. It’s only a few dollars more, but you get True RMS accuracy and CAT III 600V safety, which means you can trust your readings and stay safe even if you accidentally probe a live circuit. The Assark is simpler and cheaper, but it lacks those safety ratings, and beginners are exactly the people who need the most protection.
Is the AstroAI DM200M worth the extra money over the Assark?
In my testing, yes — absolutely. The AstroAI costs more, but it measures AC current, has NCV detection for finding live wires, and uses ceramic fuses rated for CAT III 600V. The Assark can’t measure AC current at all and has no NCV. If you ever work with household AC power, the AstroAI is worth every penny for the safety features alone.
Can the Assark multimeter measure AC current?
No, it cannot. The Assark 620A only measures DC current, so you’re limited to things like car batteries, small motors, and basic DC circuits. If you need to measure AC current for appliances, outlets, or wiring, you have to go with the AstroAI DM200M which handles both AC and DC current.
Which multimeter has better safety features?
The AstroAI DM200M wins this hands down. It has two ceramic fuses rated F250mA/250V and F10A/250V that are explosive-proof, plus it exceeds CAT III 600V safety standards. The Assark has basic fuses and CE, RoHS, and UL certifications, but no CAT rating. For anything beyond low-voltage electronics, the AstroAI is the safer choice.
Which meter is more portable for carrying in a pocket?
The Assark is much more portable. It weighs just 0.18 pounds and measures only 3.94 x 1.97 x 1.1 inches — it genuinely disappears in a pocket. The AstroAI is larger at 5.91 x 3.94 x 1.97 inches and heavier, so it’s better suited for a toolbox or glove box. If you need a meter to carry everywhere, the Assark wins on size.
Do both multimeters have a backlit display for working in dark areas?
Yes, both the AstroAI DM200M and the Assark 620A have backlit LCD displays, so you can read measurements in dimly lit basements, attics, or under a car hood. The AstroAI also has data hold and max value recording, which makes it easier to capture readings in tight spaces where you can’t see the screen directly.
My Final Verdict
The AstroAI DM200M is my clear winner for anyone who needs a reliable, safe multimeter for home or auto work. Its True RMS accuracy, CAT III 600V safety rating with ceramic fuses, and NCV detection make it far more capable than the Assark for only a small step up in price. The Assark 620A is best if you only need basic DC voltage checks and want the smallest possible pocket meter at 0.18 pounds.
If you’re on the fence, ask yourself this: will you ever measure AC current or need to know a reading is truly accurate? If yes, stop hesitating and get the AstroAI. If you’re just checking car batteries and continuity, the Assark will do fine.
