Just curious if anyone has a meter that will automatically convert FPM to CFM? I have a cheap Extech anomometer that does FPM but not CFM. Any recommendations?
The Fieldpiece STA-2 will do it. Of course you have to enter the duct size and take traverse readings to be accurate.
If I hired a licensed professional air balancing contractor, and they pulled a FP out of the truck...

what would they need to impress you?

if a tool performs the function it is intended and is accurate, what else do you need?

Meanwhile, the National Park Service, administered by the U.S. Department of the Interior, asks us to "Please Do Not Feed the Animals". Their stated reason for this policy "... the animals become dependent on handouts and will not learn to take care of themselves."

Looks good but I am considering the Testo 417. I kind of like the idea of having the vanes vs the hot wire.
I use the testo 410-2, it works well and have hand no problems with it. I like how it measures humidity, temp and fpm

Most anemometers today have built in cfm conversion. However, you still need to know the duct size or free area of the grille.
I use the FPM function often.
Knowing the face velocity of vents is very important in trouble shooting issues.
If you know what size vent you have, and are familiar with manual D, then knowing the velocity will give you the information you need.
