1. "one look at the PCB" is not enough for much. If it were, we would all be experts at everything. Ah, but I forgot: you are an (self-proclaimed) expert...
2. What exactly do you claim is a lie?
We are!

Joe: If I'm reading it right this is a meter where the input goes directly from the volts jack to the IC with only R16 and R17 in between. The PTC is on a separate circuit (after going through the range switch!)
The fact that Intertek has certified the UNI-T UT125C is certainly relevant to the issue at hand. But the baseless or irrelevant dribble you posted certainly isn't.
Apart from your "anticipating being disappointed by the Intertek Shenzen (sic) branch", do you have anything to say based on facts relevant to the issue at hand?

perhaps refrain from the baseless claims and "anticipating being disappointed" sort of comments a little bit?
Free meters!!! It's been a while since anyone has "reached out" to me with such an offer.
... you can certainly spot creepage and clearance insufficiencies.

I'm torn. You could accept it and zap it.
Was it Dave or you that did a bad 'review' of something and the manufacturer put it on their web page anyway? I don't remember.
(Bad meter! Bad!)
HIOKI also "reached out" to me a while ago. I use some of their equipment for industrial work. I don't believe they are certified.

That's common for the Japanese meters, they do self certification to the standard.
But as opposed to the Chinse companies, the Japanese actually do do it and take it seriously.

That's common for the Japanese meters, they do self certification to the standard.I'm not sure about that - I'd emailed Sanwa and Hioki asking for Certificate of Conformance or any proof about their multimeter 61010 claims.
ANENG 61010 certificate is just for a 3V battery-powered device, no hazardous energy connected to it. chinese reports can be very hokey, skipping many tests.
Engineers can design to their heart's content and think it's all good- but testing is done to prove the PC board spacings are adequate, components etc. work and it stays reasonably safe.
...
No, they have a room full of meter zapping equipment and test it themselves at every stage during development. Find the weak points and eliminate them. Third party testing only happens after the meter is fully production-ready.
Hioki just skips the last step.

Hioki just skips the last step.You don't actually know that for sure, do you? Unless you have worked with any DMM manufacturer development team at any point in your life, which I am certain you didn't...
"Internal conformance testing" just what is this exactly? The Honour System.

A good question would be: is there any verified information how many industrial accidents were caused by using UNI-T meters..?
A research, by numbers, how much more accidents happen by using UNI-T than Fluke?
I would like to see that information..
...
...
I choose to believe it because:
a) Hioki are reputable in the same way that Fluke/Brymen/Amprobe are reputable.
b) They don't sell meters for $25 on Aliexpress
c) I've seen Hioki Teardowns
d) Joe's zapped some Hiokis
e) Dave says Hioki do the internal testing

In your dreams. Please be realistic, who would pay for such information to be researched and published, and in any case, how would you guarantee that the information wouldn't be "fudged"?
This is exactly why we have mandated safety standards and independent testing and certification companies. And it is also exactly why we, as consumers, should prefer products that are independently tested and certified vs. products that are not.
Thanks for a good laugh! c) above is absolutely priceless!
Feel free to point out any safety issues:

which is safer, a Chinese product certified by Intertek or a self certified Japanese product?
