Will this give accurate readings of ambient air temperature?

Yes, but you would have to have the tip off of a table or whatever that might be a different temperature and hold it in your hand by the dial. All of these are able to be calibrated. Put in a cup of ice and set the dial to 33°.

What country is this made in?

The company Supco is located in Bronx, NY at Supco.com, had it awhile, still works well if that helps.

can this be calibrated by nut on back for rotating dial?

I believe so. There is a nut on the back, but I haven't had to recalibrate mine yet.

What is the diameter of the stem? I've got a 3/16" hole that I'd like it to fit into

The one I have measures .150", so it should easily fit into a 3/16" hole which is .1875".
