I agree with Fungus that the BM857/859 are quite capable and seem reasonably "rugged", although not to the level of a 28II.
The BM859 is really old design.
And is that a really bad thing? I don't really know, but the quality is certainly there - my BM857 is a pre production model of 2002 and it looks and still feels quite the meter.
Why such massive number of counts for the field? Also, would connectivity be really killer? Unless you want to play in the processmeter arena...
Why counts? Because meters can have dual use.
Usually you don't need 60,000 counts, 0.05% DC, 0.06% ohms, and 0.075% current for the field, but it's nice to have for the lab.
This product has now been a little bit delayed because the option of a Bluetooth footprint is being added, so that that capability can be added in a future model without a design or safety re-certification presumably. They wanted to slip it in before sending for UL testing. I have asked if the firmware can support it and if users can then simply solder in their own Bluetooth module, that's a maybe
I see your reasoning. Well, the 60000 counts is great if it can be as fast as the Brymen or the 187/189 with 50000 counts. The U1282A with 60000 counts is slow.
You may be able to get away with safety if the footprint is there, but obviously that will depend entirely on regulations at the time of release. Also, you will still require some additional testing for intentional irradiators and EMI susceptibility tests - after all, you need to know if the multimeter can survive a nearby zap.
That meter sounds suspiciously close to being some Brymen variant close to BM857/859 family... Which is a good thing..
Nah. Brymen meters do have rebrands but they still look exactly like Brymens.

Although Brymen as an OEM is known for keeping the same mold, Amprobe is big enough to create their own. The specs and the overall arrangement of buttons, jacks, range switch is identical to the BM857.
