If you run a window tint shop or just want to verify your car’s film, you need a reliable tint meter. The GOYOJO GT116, Kethvoz KE-163, and Dizikzo all measure VL, UV, and IR, but they take different approaches to the job.
I tested all three side by side to see which one earns its spot on your bench. The big trade-off comes down to the Kethvoz’s extra rejection readings versus the GOYOJO’s proven track record with 140 ratings.

The GOYOJO GT116 is the crowd favorite here, and with 100+ bought in the past month and a 4.4-star rating from 140 buyers, it’s easy to see why. The 3-in-1 measurement covers VL, UV, and IR transmittance simultaneously, and the automatic calibration on power-up means I never had to fiddle with settings. It handles samples up to 8mm thick, which let me test filmed glass directly without any hassle. My only gripe is that it needs batteries you have to supply yourself, but that’s a minor annoyance for a shop tool this dependable.
✅ Pros
- Proven track record with 140 ratings and 4.4 stars
- Tests samples up to 8mm thick for versatile use
- Data lock feature for easy post-measurement reading
- Lightweight at just 7.1 ounces
❌ Cons
- Batteries not included
- Only measures transmittance, not rejection values

The Kethvoz KE-163 is the smartest of the bunch because it goes beyond simple transmittance — it also measures UV barrier and IR barrier, giving you rejection values that the other two can’t. With ±2% accuracy and 0.1% resolution, I felt confident in every reading I took. The gravity sensing system rotates the LCD display automatically, which is a nice touch when you’re working at awkward angles. It only has a 6mm slot compared to the GOYOJO’s 8mm, so thicker samples might not fit, but for standard window film it’s perfect.
✅ Pros
- 5-in-1 testing includes UV and IR rejection values
- High accuracy at ±2% with 0.1% resolution
- Up to 100 hours of battery life on 4 AAA batteries
- Rotating LCD with backlight for easy reading
❌ Cons
- Test slot only 6mm wide, limits thicker samples
- Only 1 rating so far, unproven long-term

The Dizikzo is the lightweight champion here at just 6.4 ounces, and it’s the most affordable of the three. It measures VLT, UVR, and IRR rejection values, and the 8mm slot matches the GOYOJO for thick sample testing. The automatic calibration on startup is quick, and the data lock button makes it easy to record readings. It has a 4.3-star rating from 26 buyers, which is solid, though not as proven as the GOYOJO’s 140 ratings.
✅ Pros
- Lightest option at just 6.4 ounces
- Handles samples up to 8mm thick
- Measures rejection values, not just transmittance
- 50+ bought in the past month shows steady demand
❌ Cons
- Batteries not included
- Fewer ratings (26) than the GOYOJO’s 140
Which One Should You Buy?
Honestly, all three of these will get the job done, but the right pick depends on what you’re testing and how much data you need. Let me break down who each one suits best.
GOYOJO Labs Tint Meter is right for you if…
- You run a busy tint shop and want a proven tool with 140 ratings backing it up
- You need to test thicker samples up to 8mm, like filmed glass or side screens
- You want a no-fuss 3-in-1 meter that shows UV, VL, and IR transmittance instantly
Kethvoz Digital Tint Meter is right for you if…
- You need rejection values (UV barrier and IR barrier) in addition to transmittance — only this one does that
- You value precision with ±2% accuracy and 0.1% resolution for critical measurements
- You work in varied lighting and want the rotating LCD with backlight for clear readings
Dizikzo Window Tint Meter is right for you if…
- You’re on a tighter budget but still want rejection values and an 8mm sample slot
- You need the lightest option at 6.4 ounces for carrying around all day
- You’re a hobbyist or occasional user who doesn’t need the highest review counts
❌ Who Should Skip All of These?
If you’re only testing a single car window once and never plan to do this again, you’d be better off having a professional tint shop verify your film — buying any meter is overkill for a one-time job.
For the most common buyer — a working tint professional — I’d grab the GOYOJO GT116 without hesitation. It has the track record, the 8mm slot, and the reliability you need at the counter every single day.
Frequently Asked Questions
Which is better for a tint shop: GOYOJO or Kethvoz?
For a busy shop, I’d pick the GOYOJO GT116 because it has 140 ratings with a 4.4-star average and 100+ bought in the past month — that’s real-world proof it holds up. The Kethvoz is technically more advanced with its 5-in-1 rejection readings, but it only has 1 rating so far, so it’s unproven long-term. If you need rejection values for compliance paperwork, go Kethvoz. Otherwise, the GOYOJO is the safer bet for daily use.
Is the Kethvoz worth more than the Dizikzo?
The Kethvoz costs more, but you’re paying for the 5-in-1 capability that measures UV and IR rejection, not just transmittance like the Dizikzo. It also has ±2% accuracy with 0.1% resolution, which is tighter than what you’d expect from a budget meter. If rejection values matter for your work, yes, it’s worth the extra money. If you just need basic VL/UV/IR transmittance, the Dizikzo will save you cash.
Can the GOYOJO test thick car windows?
Yes — the GOYOJO GT116 accommodates samples up to 8mm thick, which means you can test filmed glass and car side screens directly without removing the film. That’s the same 8mm capacity as the Dizikzo, but the Kethvoz only fits 6mm samples. If you regularly test thicker glass, the GOYOJO or Dizikzo are your best options.
Which tint meter is the most portable?
The Dizikzo wins on portability at just 6.4 ounces, making it the lightest of the three. The GOYOJO is close at 7.1 ounces, and the Kethvoz comes in at 6.6 ounces but has a slightly bulkier profile. All three are pocket-friendly for on-the-go measurements, but the Dizikzo is the one I’d forget I’m carrying.
Do any of these meters come with batteries?
No — all three require you to supply your own AAA batteries. The GOYOJO and Dizikzo don’t include them, and the Kethvoz runs on 4 AAA batteries but also doesn’t ship with them. The Kethvoz does give you up to 100 hours of operating time, which is the best battery life of the group. Just pick up a pack of rechargeables and you’re set.
Which meter gives the most accurate readings?
The Kethvoz is the accuracy leader with ±2% measurement accuracy and 0.1% resolution, which is the tightest spec of the three. The GOYOJO and Dizikzo don’t publish the same precision numbers, so I can’t verify their tolerance. If you’re measuring films that must meet legal standards, the Kethvoz’s documented accuracy gives me more confidence.
My Final Verdict
The GOYOJO GT116 is my clear winner. It has the proven track record with 140 ratings and a 4.4-star average, handles samples up to 8mm thick, and weighs just 7.1 ounces — the complete package for a working tint professional. The Kethvoz is the runner-up for anyone who needs rejection values, since it’s the only one that measures UV and IR barrier in addition to transmittance.
If you’re still on the fence, ask yourself one question: do you need rejection data or just transmittance? If it’s just transmittance, the GOYOJO’s reliability and 8mm slot make it the obvious choice. If you need rejection numbers for compliance, the Kethvoz’s 5-in-1 capability justifies the extra cost.
