A while back, I worked for a small division of Litton Industries,
and at the annual inter-division "technology transfer" seminars,
I met the chief engineer of Litton's microwave oven division.

In the course of casual discussions, I found out that a good way
to determine the "microwave wattage" is to use simple calorimetry;
put a measured amount of water at a known temperature in the oven,
and run it a measured time to produce a *small* increase in
temperature. The rest is left as an exercise for the curious...

He also said that they never used one of those expensive "leakage
meters"; they just bent the leads of a NE-2 out like a dipole and
went around the seal with it. No light, no leakage.

No responsibility if these things don't work, though.
