    Jim,
    How does the sta2 compare to the aat3, I wonder why they dropped the web bulb reading on the Sta2. Thanks for all your dedication to the trade and quality testing.

    The AAT3 only measures velocity and it does not calculate CFM like the STA2. On the surface it looks like the perfect accessory, but it leaves all of the calculations and the averaging to the technician. The STA2 does it all for you. Thanks for the feedback.
