Steve,
That tester will work on 120 volt outlets but how does it test a 50 amp 140 outlet? If it is only designed to test 120 volt circuits, it is only testing one hot leg of a 240 volt circuit.

It doesn't, it can only check 110. A meter can test both sides of 220 connection (one at a time, of course!) and give the voltage readout. A meter is a good thing to have when you travel as it can help you diagnose all kinds of power problems - both 12DC and 110/220AC. I'm a little hesitant to recommend one of those $10 'made in China' specials at Harbour Freight though. We are, after all, talking about serious voltage/amperage.
