Just another datapoint from CEM: DT9969

This one will be streets ahead of the DT-9969, although it won't be dust and waterproof.
Also it may turn out to be cheaper. Although I don't know what the future Bluetooth one will sell for.
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.
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
