Model AFH2 Air Flow Hood

Brand: Dwyer Instruments, LLC

The MODEL AFH2 Air Flow Hood maintains a running average of volumetric air flow measurements and provides the ability to manually record the measurements with the manometer over a given period of time. 

The highly accurate digital manometer has an auto-zero function and will auto-zero at user-defined intervals.

In addition to these features, the unit will alert you when its battery is running low in order to avoid recording inaccurate measurements.
Features
  • Highly Durable and Easy Storage in Included Travel Case
  • No Tools Required to Set up
  • Digital manometer easily mounts to the flow hood or can be used as stand alone instrument
