have a couple of questions for all of you smart technicians! I appreciate any information you can provide.

How many technicians are measuring Wet Bulb temperatures? (out of 100 techs, how many measure wet bulb?)

Where do technicians take these measurements? Inside the building? At the return Grille? In the return duct work? in the return plenum?

What do you use to measure the wet bulb temperature?

What do you use the wet bulb measurements for?
