Hi guys, we use two of the Alnor units, and there is a switch to toggle between supply and return airflow, as we move through the rooms in a house. It it just as simple with the Testo unit? And, in tight areas, we will take our readings without the hood. Is that possible with the Testo? Thanks! I enjoyed your video.
When trying to get the best possible reading for a customer report, would it not be better to remove the registers before taking a reading to allow the full force of the air to be directed downward toward the sensors or is the difference in readings negligible?
Cody Schmitt the register is reducing the amount of cfm's flowing from the vent. If you were to remove it you would have a higher CFM reading which would be wrong.
