OK, I see very little information out there about the use of Infrared Thermometers and/or how they may or may not be used with regard to things like HVAC.
So, let me start with asking a question about wet bulb temperature. If I were to take a wet paper towel, or something similar... Place it in the path of some air flow, let it sit and allow evaporation to take place, then use a IR Thermometer to measure the temperature of that paper towel, shouldn't that give me the wet bulb temperature or it's equivalent?
How about measuring the pipe temperature? if the focus of the IR is small enough and it's aimed correctly, shouldn't a person be able to read the temperature of some tubing/pipe?
What about Outdoor Ambient temperature? If a IR meter is pointed at some object that isn't directly in the sun (not getting radiant heat from the sun) shouldn't that reading be very close to the Ambient temperature?
Other then the wet bulb temp situation above, I would not expect these readings to be accurate if moisture and/or air flow is present. What other problems might exist in trying to measure dry bulb type temperatures as described above?
