Argh! Someone stop me!
I "accidentally" picked up another Fluke 2190A:

with a 2300A this time. I just made a minimal bid, I didn't expect to win!
I also picked up a differential pressure transmitter:

(Dwyer 647, Wet/Wet Differential Pressure Transmitter)
unfortunately, I only noticed afterwards that the accuracy is very poor. Oh well.
