Anomometer

[daviddsims]

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.

what would they need to impress you?

if you are not balancing and just want to get a CFM for verifying airflow, would it be acceptable for you?

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

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

A calculator and a measuring tape.

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.
