Polycarbonate is much more brittle than polyethylene, which is also highly resistant to acids and solvents.LOL!
Calling polycarbonate brittle is like calling copper highly resistive.
Things made with PE:
sandwich bags
freezer bags
vapor barrier
food containers
Fluke meters
Things made with PC:
Bullet proof face shields
motocross goggle lenses
motorcycle helmets
explosion proof cabinets
Brymen meters
Polycarbonate is also much more brittle then a wet noodle.
And both Diamond and CBN are much more brittle then Polycarbonate.
(And no, that CBN is not Cannabinol, but that other stuff, with Boron in it.)
Also, the split banana jacks are for a function to beep at you when the probe is in the Amp jack while the selector switch is in the volt range. I blew up one of my old (el cheapo) DMM's that did not have this feature, and it has saved me multiple fuses (each EUR10 or so) in the 30 years thereafter. This is an quite important feature for me, and I think the flukes don't have that.
I'm pretty sure the same is true for Brymen)
But overall, quality is quite comparable, and as Fluke is just not affordable for me, I'd buy the Brymen anytime over the Fluke.
Even if it was a birthday present, I'd rather have the Brymen then the Fluke, as I regard it as overpriced and I dislike the idea of rewarding companies for such a policy. Brymen has a much better Performance to price ratio, and that is what I can appreciate.

The Fluke 87v has that feature (but not every Fluke model does - I'm pretty sure the same is true for Brymen)
Something is missing from the EEVBLOG lineup.
They won't let me sell the 869.
The 869s looks fine in red. Where's the 121?
I note you haven't quibbled about the chemical resistance, and missed off your list of PE uses "bottles for hydrofluoric acid", which I'll grant is a fringe case, so perhaps "fuel can" is more mainstream.
Take a Fluke 87 V and Brymen 869S, chill them down to oh, -10 Celcius or so, then drop them onto concrete from 3m.
If you are using the meter handheld all day, don't forget the weight. Beyond just length and width, also consider the height. The following weight are measured with Envelop AAA and Lithium 9V batteries
Fluke 179: 405g, 43mm
Bremen 756: 419g, 51mm
Fluke 87v: 508g, 52mm
Bremen 869s: 627g, 64.5mm
I personally find 869s to be the only model that is too thick, too big, and too heavy for handheld job where you have to hold it for an extended period of time, as it is 55% heavier than the 179. The Fluke 179 is the sweet spot for handheld in my book due to its smaller size and weight, with the 756 being a close second if you need more features.

Well, it seems you never had a fluke for a long time to work with.
At home I got a BM869s, at work we have tons of fluke meters, mostly 87V, some 187/189 and two 289, 15 or more 117 and 179 models.
We still have a 87 from 1990, it was calibrated over 30yrs every year without any issues.
I let my brymen calibrate in the year I bought it (2020) and it must be re-adjusted to reach it´s own specs...
I don't know why anyone would use an 87V or 869 handheld or in the field, they are basically high feature high precision bench meters.
My choice for handheld field use would be the likes of the BM235 or Fluke 117.
Although I can appreciate the likes of the ruggedised Fluke 27-II for extreme field use.
Because I might be doing anything from poking around in a 3ph panel board to measuring charge current in a small fire alarm system.
I'd be happy to use the 869S but for its size.
There is the Kane 555:
... But they dropped the 15V zener mode.
Some users, myself included, have reported a bit of drift with the BM869 that may be an issue depending on your requirements: https://www.eevblog.com/forum/testgear/bymen-bm869-measurement-of-dcv-linearity/
Fortunately the calibration/adjustment procedure for the BM869 is well known and easy to perform: https://www.jackenhack.com/calibrating-brymen-bm-series-multimeter/
If you calibrate/adjust the 500,000 count modes, you won't be disappointed.

I don't know the 87V is the meter I use in the field. It's good but I don't feel it's a high precision meter.

Well, it was when it was first introduced 35 years ago

http://cn.kanetest.co.kr/shop.php?goPage=GoodDetail&g_code=20220330171318692&cat_no=2
Basically a 121GW platform but with triple display, true energy measurement and motor stuff. But they dropped the 15V zener mode.
Or maybe:
https://catalog.chauvin-arnoux.com/fr_en/mtx-3291.html
Smaller in all dimentions, weighs less at 570g
Or one of the Gossens maybe, but IIRC they won't be any smaller.

As for -10C, well they make snowmobile helmets, goggles and face shields from PC too.
HDPE is a good material for sure. I'm just not convinced it's as tough as or any better than PC. HDPE is less expensive than PC though so I guess that's why Fluke can make meters that are so budget friendly.
Are you saying that from your professional experience Brymens don't maintain calibration for long(er) periods of time?
Where did you send it to be calibrated (if not in-house?). Thanks![]()
