Is this particle counter measurement volume for m³ or ft³. — 1 Answer

From Extech:
The VPC300 only provides Raw counts. So your meter displays the actual count for particles of the channels selected:
2.5 μm = 365 particles of 2.5 microns
5.0 μm =70 particles of 5 microns
10 μm =34 particles of 10 microns
This information is meant to be used to maintain a cleanroom standard(such as ISO 14644-1:1999).
You can calculate the value by using the air flow rate value from the VPC300 pump: 0.1cu.ft./min, 0.0028cu.m./min.
The longest it can run would be 1 minute. If you need it to run for a longer duration you can set the cycles to suit your application.
