I review rough HVAC installations and set balance flows for residential buildings. I was able to use a 4200 for a short while and it saves a great deal of labor time. The instrument also has all the other elements required of a HVAC specialist. Temperature, Dry and Wet, humidity plus the all important cubic feet per minute information.
