Individual Product Breakdown
I spent time comparing the specs, reading through user feedback, and thinking about real-world use for both of these ANENG meters. Here’s what I found in each one.

The SZ02 is the more feature-packed of the two, and the 9999-count TRMS resolution gives you finer readings than the 613’s 4000 counts. I really like the non-contact voltage (NCV) detection with sound and light alarms, plus the dual torch lighting that makes working in dark crawl spaces much easier. It also measures temperature, which the 613 doesn’t do, and comes with a temperature line in the box. The only downside is that with all those accessories and the silicone cover, it’s a bit more to keep track of than the simpler 613.
✅ Pros
- Higher 9999-count resolution for more precise readings
- NCV detection with sound and light alarms for safety
- Dual torch lighting for dimly lit work areas
- Includes temperature measurement and probe
❌ Cons
- More accessories means more to manage and potentially lose
- No calendar or clock features like the 613

The 613 is the simpler, more straightforward option, and its large LCD screen makes readings easy to see even in bright light. What sets it apart is the built-in calendar, alarm clock, and real-time temperature display — handy extras that let you track time while you work. With 4000 counts, it’s less precise than the SZ02’s 9999 counts, but for most household DIY tasks, that’s plenty. It’s a great pick for beginners who want a clean, uncluttered interface without all the extra accessories.
✅ Pros
- Large LCD screen that’s readable in strong light
- Built-in calendar, alarm clock, and real-time temperature display
- Auto mode switches between functions without manual selection
- Compact size at just 1.97 x 1.97 x 0.79 inches
❌ Cons
- Lower 4000-count resolution compared to SZ02’s 9999 counts
- No NCV detection or torch lighting
Which One Should You Buy?
Honestly, both of these meters will get the job done for most electrical work, but the right pick comes down to what you value more: higher resolution and smart features, or a giant display with extra timekeeping tools. Let me break it down by buyer type so you can match your needs to the right tool.
ANENG SZ02 is right for you if…
- You need the extra precision of 9999-count TRMS readings for more detailed troubleshooting
- You work in dark spaces and want the dual torch lighting plus NCV detection with audible alarms
- You want temperature measurement capability built into the same tool you’re already carrying
ANENG 613 is right for you if…
- You want the easiest-to-read large LCD screen, especially in bright daylight or dim environments
- You like having a calendar, alarm clock, and real-time temperature display right on your meter
- You’re a beginner who wants auto mode to switch between functions without manual range selection
❌ Who Should Skip All of These?
If you’re a professional electrician doing heavy-duty work daily, you’ll probably want a rugged, high-end clamp meter with CAT III or CAT IV safety ratings and higher current measurement capacity. These are great for DIY and light professional use, but they’re not built for industrial-grade abuse.
For the vast majority of home users and hobbyists, I’d point you toward the ANENG SZ02 — that 9999-count resolution and the added NCV and temperature features give you more capability for just a little more complexity. It’s the smarter long-term investment.
Frequently Asked Questions
Which is better for home DIY, the ANENG SZ02 or the ANENG 613?
For home DIY, I’d pick the ANENG SZ02 without hesitation. The 9999-count TRMS resolution gives you more precise readings than the 613’s 4000 counts, which matters when you’re testing sensitive electronics or checking battery health. Plus, the NCV detection and dual torch lighting make it safer and easier to work in awkward spots around the house. The 613 is fine for basic outlet checks, but the SZ02 handles a wider range of tasks with better accuracy.
Is the ANENG SZ02 worth the extra money over the ANENG 613?
Here’s the thing — both meters are priced the same in the current listings, so you’re not actually paying more for the SZ02. That makes it a no-brainer for me. You get more than double the count resolution (9999 vs 4000), temperature measurement, NCV detection, and dual flashlights for the same price. If both are equal in cost, the SZ02 is clearly the better value.
Which multimeter has a better display for outdoor or bright light use?
The ANENG 613 wins this one thanks to its large LCD screen that’s specifically designed to be readable in strong light. The SZ02 has a backlit screen, which helps in the dark, but the 613’s bigger display with better contrast makes it easier to read in sunlight. If you’re working outside on a sunny day, the 613 is the more comfortable choice.
Can both meters measure temperature?
No, this is a major difference between them. The ANENG SZ02 includes temperature measurement capability and comes with a temperature line in the box, so you can start measuring right away. The ANENG 613 does not measure temperature at all — it only displays the ambient room temperature on its screen. If you need to check component temps or HVAC systems, the SZ02 is the only option here.
Which one is better for a beginner who’s never used a multimeter before?
I’d actually recommend the ANENG 613 for absolute beginners. Its auto mode automatically switches between AC/DC voltage, current, resistance, continuity, and capacitance without you needing to select a mode or range manually. The large LCD is also more forgiving when you’re learning to read values. The SZ02 has more features, but that can feel overwhelming when you’re just starting out.
Which multimeter has better safety features?
The ANENG SZ02 is the safer choice here. It has double ceramic fuse anti-burn protection to guard against overloading, plus a silicone cover that protects against electric shocks and drops. It also includes non-contact voltage testing with sound and light alarms, which lets you detect live AC voltage without touching test leads to anything. The 613 is reliable, but it doesn’t offer that same level of protective design.
My Final Verdict
The ANENG SZ02 is my clear winner here. That 9999-count TRMS resolution doubles the 613’s 4000 counts, and the added NCV detection, temperature probe, and dual torch lighting make it a far more capable tool for roughly the same money. The 613 is still a solid choice, but only if you prioritize the large LCD and calendar features over raw capability.
If you’re still on the fence, ask yourself this: do you want more precision and safety features, or a bigger screen with a clock? For most buyers, the SZ02’s extra functionality wins every time — you’re getting a smarter meter without paying a premium.
