Review on 🌬️ Enhance Your Surroundings with the AAB ABM 200 Airflow Environmental Bluetooth Device by Seth Gomez

This meter takes the guesswork out of troubleshooting and balancing your Central Air HVAC system. The iPhone software does some things that don't make sense, but the basic data is there. I have not used their CFM calculations because they only use approximations for case limits. However, measurements of air velocity, dry and wet bulb temperatures, and humidity are invaluable. Combine the output with multiple calculations in one spreadsheet for a comprehensive view of your HVAC airflows.
