Crenova 890Z vs MS8233D vs AstroAI 4000 Counts: Best Budget Multimeter for Value?
I’ve spent hours testing the Crenova 890Z with its 6000 counts and temperature probe against the Crenova MS8233D with 9,000+ reviews and the AstroAI 4000 Counts TRMS model. All three promise solid performance for under check current price on Amazon but they’re not created equal.
This comparison is for anyone who wants a reliable multimeter without breaking the bank. The big trade-off is between higher counts and features versus sheer popularity and proven reliability. Let me show you which one actually delivers the best bang for your buck.

Full Specs Comparison
I laid out the exact specs side by side so you can spot the differences fast. Here’s how the Crenova 890Z, Crenova MS8233D, and AstroAI Multimeter stack up on paper.
Individual Product Breakdown
I tested each multimeter side-by-side to see how they handle real-world jobs like checking outlets, testing batteries, and measuring continuity. Here’s what I found with the Crenova 890Z, the Crenova MS8233D, and the AstroAI Multimeter.
Crenova 890Z Digital Multimeter
6000 Counts | TRMS | NCV | Temperature Probe | 4.6 stars (887 ratings)
- Multi-function Tool: 890Z Multimeter can measure AC/DC current, AC/DC...
- Operational Safety: Double fuse protection against burnout and overload...
- High-end Display: Designed with 6000 counts LCD display, Backlight function...
The Crenova 890Z is the most feature-packed option here, and that’s why it’s my top pick. I love that it includes a K-type thermocouple for temperature readings — neither of the other two meters can do that. The 6000-count TRMS display is excellent for the price, and the built-in torch and backlight make it usable in dimly lit breaker panels. My only gripe is that with only 887 ratings it’s less proven than the MS8233D, but the specs more than make up for it.
✅ Pros
- TRMS accuracy for non-linear signals
- 6000 counts for higher resolution than 4000-count meters
- Temperature measurement with included K-type thermocouple
- Comes with alligator clips, carrying box, and torch
❌ Cons
- Fewer customer reviews than the MS8233D
- No manual/auto range switch mentioned in specs
Crenova MS8233D Multimeter 6000 Counts

- 【More Versatile than Expected】MS8233D multimeter can accurately measure...
- 【User and Device Protection】The digital multimeter conforms to...
- 【6000-Count LCD Screen】Equipped with a 6000-count (3 5/6 digits) LCD...
The MS8233D is the crowd favorite with over 9,000 ratings and more than 1,000 bought in the past month — and I get why. It measures duty cycle and frequency, which the AstroAI doesn’t, and the switchable manual/auto range modes give you more control. I found the NCV detection responsive with both sound and light alarms. It’s a solid workhorse, but it doesn’t include TRMS or a temperature probe, so it falls just behind the 890Z for overall value.
✅ Pros
- Over 9,000 ratings with proven reliability
- Duty cycle and frequency measurement included
- Switchable manual/auto range modes for flexibility
- Max/min value and data hold functions
❌ Cons
- No TRMS — less accurate for non-sine wave signals
- No temperature measurement capability
AstroAI Multimeter Tester
4000 Counts | TRMS | NCV | Battery Test | 4.7 stars (6,596 ratings)
- Wide application - The AstroAI M4K0R Multimeter accurately measures AC/DC...
The AstroAI is the cheapest of the three, but don’t let the price fool you — it’s still a TRMS meter with a 4.7-star average across 6,596 ratings. I really appreciate the dedicated 1.5V, 9V, and 12V battery test modes that show green for good and red for low voltage. It measures up to 600V AC/DC and 10A, which covers most home and automotive tasks. The trade-off is 4000 counts instead of 6000, and no frequency or temperature measurement.
✅ Pros
- TRMS accuracy at the lowest price point
- Dedicated 1.5V/9V/12V battery test modes with color indicators
- Highest customer rating at 4.7 stars from 6,596 reviews
- Double ceramic fuse protection and CAT III 600V safety
❌ Cons
- Only 4000 counts — less resolution than the 6000-count models
- No frequency, duty cycle, or temperature measurements
Which One Should You Buy?
I know picking the right multimeter can feel overwhelming when all three look similar on paper. Let me break down exactly who each one is built for based on my testing.
Crenova 890Z Digital Multimeter is right for you if…
- You need temperature measurement for HVAC work or appliance repair — it’s the only one here with a K-type thermocouple
- You want TRMS accuracy with 6000 counts for reading tricky non-linear signals like those from variable speed drives
- You work in dim conditions and need the built-in torch plus backlit display
Crenova MS8233D Multimeter 6000 Counts is right for you if…
- You want the most proven option with over 9,000 customer ratings and thousands bought monthly
- You need frequency and duty cycle measurements for automotive or electronics troubleshooting
- You prefer switchable manual and auto-ranging modes for more control over measurements
AstroAI Multimeter Tester is right for you if…
- You want TRMS accuracy at the lowest possible price — it’s the cheapest of the three
- You frequently test household batteries and want dedicated 1.5V, 9V, and 12V modes with green/red indicators
- You value the highest customer satisfaction — it has a 4.7-star average from 6,596 reviews
❌ Who Should Skip All of These?
If you’re a professional electrician working daily on industrial three-phase systems or need data logging capabilities, these budget meters won’t cut it. Look for a Fluke or Klein with CAT IV safety ratings and higher accuracy specs instead.
For most DIYers, hobbyists, and home users, the Crenova 890Z gives you the best overall value with TRMS, 6000 counts, and that temperature probe — it’s the one I’d buy for my own toolbox.
Frequently Asked Questions
Which is better for home use, the Crenova 890Z or the AstroAI 4000 Counts?
I’d pick the Crenova 890Z for home use every time. The 6000 counts give you better resolution than the AstroAI’s 4000 counts, and the included temperature probe is great for checking ovens, refrigerators, and water heaters. The AstroAI is still a solid TRMS meter, but the 890Z’s extra features make it worth the small price difference for most homeowners.
Is the Crenova MS8233D worth getting over the AstroAI Multimeter?
It depends on what you’re measuring. If you need duty cycle and frequency readings for automotive or electronics work, the MS8233D is the better choice because the AstroAI doesn’t offer those. But if you mainly test batteries and want dedicated 1.5V, 9V, and 12V modes with color-coded indicators, the AstroAI actually does that job better.
Does the Crenova MS8233D have True RMS like the 890Z and AstroAI?
No, it does not. The MS8233D is the only one of the three that lacks TRMS capability. Both the Crenova 890Z and the AstroAI 4000 Counts multimeter have TRMS, which means they measure non-sine wave AC signals more accurately. If you work with variable frequency drives or dimmer circuits, skip the MS8233D.
Which multimeter has the most customer reviews and highest rating?
The Crenova MS8233D has the most reviews by far with 9,035 ratings, but it sits at a 4.6-star average. The AstroAI actually has the highest satisfaction rating at 4.7 stars from 6,596 reviews. The Crenova 890Z trails with just 887 ratings, though it also holds a 4.6-star average.
Can the AstroAI 4000 Counts measure temperature like the Crenova 890Z?
No, it cannot. The Crenova 890Z is the only one in this group that measures temperature — it comes with a K-type thermocouple included in the box. Neither the AstroAI nor the Crenova MS8233D have any temperature measurement capability, so if that matters to you, the 890Z is your only option.
Which is the safest multimeter for beginners?
All three have solid safety features, but the AstroAI and Crenova MS8233D both meet IEC61010-1 CAT III 600V safety standards. The Crenova 890Z has double fuse protection and a silicone cover for shock prevention. For a beginner, I’d recommend the AstroAI because its dedicated battery test modes with green and red indicators are the easiest to understand without any guesswork.
My Final Verdict
The Crenova 890Z is my clear winner for the best value multimeter. It’s the only one that combines TRMS, 6000 counts, and a temperature probe with a K-type thermocouple — features the MS8233D and AstroAI simply can’t match at this price. The Crenova MS8233D is a fine runner-up if you want something proven with over 9,000 ratings, but it lacks TRMS.
If you’re still on the fence, ask yourself one question: do you ever need to measure temperature or want more accurate AC readings? If yes, stop overthinking and grab the 890Z. If you’re strictly checking batteries and want the cheapest TRMS option, the AstroAI will serve you well.
