The Lutron SP-9202 is one of the latest releases from Lutron and represents the top function model. Air flow can be calculated from duct size, and Dew Point, Wet bulb, Heat Index, Wind chill and other variables are also calculated from the combined measurements. An exceptional combination of readings in a tiny package.
