The SZ301 is the one I’d recommend to most beginners, and it’s easy to see why it’s the best seller with over 2,471 ratings and 3K+ bought in the past month. The DC voltage accuracy of ±(1%+5) is solid for the price, and the 200MΩ resistance range is the widest of the three, which helps when testing insulation or components with high resistance. It comes with a silicone protective case, two pre-installed AA batteries, and two test leads right out of the box. The only real downside is there’s no backlit display, so you’ll need decent lighting to read the screen in dim areas.
✅ Pros
- Widest resistance range at 200MΩ
- Capacitance measurement up to 2mF
- Includes silicone case and pre-installed AA batteries
- Proven track record with 4.4 stars from 2,471 reviews
❌ Cons
- No backlit display
- No frequency measurement

- User-friendly:SZ302 amp meter with backlit display greatly enhance the reading...
The SZ302 is the smart choice if you work in dim environments, thanks to its backlit LCD and built-in flashlight that the SZ301 lacks. It also has a rubberized, waterproof, and dustproof case that gives it a more durable feel than the standard silicone sleeve on the SZ301. The compact box-type design with a stretchable support frame on the back makes it easy to prop up on a bench, though it’s only been reviewed 13 times so far. At just 0.6 grams, it’s incredibly light, but that also means it might feel a bit flimsy compared to the SZ301’s more established build.
✅ Pros
- Backlit LCD screen for dim conditions
- Built-in flashlight for night work
- Rubberized waterproof and dustproof case
- Foldable support stand on the back
Only 13 customer reviews so far

The SZ303 is the lightest and most affordable of the three at just 100 grams, making it the ultimate pocket meter for quick checks on the go. It’s the only one here that measures frequency (200Hz to 2MHz), which is a nice bonus if you’re troubleshooting motors or signal circuits. The backlit screen is also a welcome feature, and the low-battery indicator is a thoughtful touch that the others don’t mention. However, it runs on AAA batteries instead of AA, and with only 36 reviews at 4.3 stars, it’s less proven than the SZ301.
✅ Pros
- Only model with frequency measurement up to 2MHz
- Lightest at just 100 grams
- Backlit screen and low-battery indicator
- Comes with AAA batteries included
❌ Cons
- Uses AAA batteries instead of AA
- Only 36 reviews, less proven track record
Which One Should You Buy?
Honestly, the “best” ANENG for you comes down to where you’ll use it and what you care about most — screen visibility, portability, or proven reliability. Let me match each meter to the right kind of buyer.
ANENG SZ301 Digital Multimeter with Case is right for you if…
- You want the most proven option with 2,471 ratings and 3K+ bought in the past month — you like buying what others already trust.
- You test insulation or high-resistance components and need the 200MΩ resistance range that the other two models don’t offer.
- You want a complete kit with a silicone case, two test leads, and pre-installed AA batteries so you can start measuring right away.
ANENG SZ302 Multimeter with Backlit LCD is right for you if…
- You often work in dim garages, attics, or under dashboards where the backlit LCD and flashlight make readings actually visible.
- You drop your tools — the rubberized waterproof and dustproof case gives you extra protection the SZ301’s silicone sleeve doesn’t.
- You like the foldable support stand on the back so you can prop the meter up hands-free while probing with both hands.
ANENG SZ303 Digital Multimeter Tester is right for you if…
- You need frequency measurement from 200Hz to 2MHz to troubleshoot motors, signal circuits, or household outlets — none of the others do this.
- You want the lightest pocket meter at just 100 grams that disappears in your bag or toolbox.
- You’re on the tightest budget and just need the basics — voltage, current, resistance, continuity, and diode testing.
❌ Who Should Skip All of These?
If you’re doing professional electrical work that requires CAT III or CAT IV safety ratings, true RMS accuracy, or data logging, skip these budget meters entirely and look at a proper Fluke or Klein. These ANENGs are fine for hobby work, but they don’t have the safety certifications or precision you’d want for commercial jobs.
For the most common buyer — a beginner or DIYer who wants a reliable, well-reviewed meter without spending much — I’d grab the ANENG SZ301. It has the widest resistance range at 200MΩ, a proven track record, and everything you need in the box. If you work in dark spaces, pay the small difference for the SZ302 and its backlit display.
Frequently Asked Questions
Which is better for a beginner: the ANENG SZ301 or the SZ302?
For a complete beginner, I’d say the SZ301 is the better pick because it’s been tested by over 2,471 reviewers and has a proven track record. It also offers a wider 200MΩ resistance range, which is handy when you’re learning to test all sorts of components. The SZ302’s backlit screen is nice, but it only has 13 reviews so far, so you’re taking a small gamble on a newer product. If you mostly work in good lighting, the SZ301 is the safer, more versatile choice.
Is the ANENG SZ302 worth paying more than the SZ303?
That depends on what “more” means to you. The SZ302 gives you a backlit LCD, a built-in flashlight, and a rubberized waterproof case — all genuinely useful for working in dark or rough environments. But the SZ303 adds frequency measurement up to 2MHz, which the SZ302 doesn’t have, and it’s lighter at just 100 grams. If you need frequency testing, the SZ303 is worth it. If you need visibility and durability, the SZ302 justifies its price.
Can the ANENG SZ301 measure frequency like the SZ303?
No, it can’t. The SZ301 measures AC/DC voltage up to 600V, current from 2mA to 10A, resistance up to 200MΩ, and capacitance up to 2mF, but frequency isn’t in its spec list. The SZ303 is the only one of the three that measures frequency, covering 200Hz to 2MHz with an input voltage range of 1V to 50V AC RMS. If you’re troubleshooting motors or signal circuits, the SZ303 is your only option here.
Which ANENG multimeter has the best display for outdoor or bright sunlight use?
The SZ302 is the winner for display visibility because it has a backlit LCD screen, which the SZ301 lacks entirely. The SZ303 also has a backlit screen, so both are better than the SZ301 in dim conditions. That said, neither is specifically designed for direct sunlight — LCDs can still wash out in harsh light. For dark garages or night work, the SZ302’s backlight plus flashlight combo is the most practical.
Are the ANENG SZ301 and SZ302 accurate enough for automotive battery testing?
Yes, both are fine for basic automotive battery checks. They measure DC voltage from 200mV to 600V with the SZ301 offering ±(1%+5) accuracy, which is plenty for checking a 12V car battery. The SZ302 covers the same 200mV to 600V DC range, and its compact size makes it easy to handle around the engine bay. Just remember neither has true RMS, so don’t expect lab-grade precision — but for a quick battery health check, they’ll do the job.
Should I buy the ANENG SZ301 or spend a bit more for a more expensive brand like Fluke?
If you’re a beginner or hobbyist, the SZ301 is honestly all you need — it covers voltage, current, resistance, capacitance, and diodes for a fraction of what a Fluke costs. Fluke meters offer better safety ratings (CAT III/CAT IV), true RMS, and higher build quality, but those matter most for professional electricians working on live commercial systems. For home electronics, car repairs, or school projects, the SZ301’s 600V range and 200MΩ resistance will handle everything you throw at it. Save your money unless you’re doing professional work.
My Final Verdict
The ANENG SZ301 is my clear winner for most beginners. It has the widest resistance range at 200MΩ, the most proven track record with 2,471 ratings, and includes a silicone case and pre-installed batteries right out of the box. The SZ302 is the runner-up, best for anyone who works in dim spaces and needs that backlit LCD and flashlight.
If you’re still on the fence, think about where you’ll actually use the meter most. If it’s a well-lit workbench or garage, the SZ301 gives you the most capability for your money. If you’re crawling under dashboards or into dark attics, pay the small difference for the SZ302’s backlight and built-in flashlight.
