Thank you for purchasing this wireless
air flow meter. This meter is specially
designed for HVAC&R application that
combines those required measurements,
like Air Velocity, Air volume, Temp., RH, 
WBT, DP, and CO2 in one handy meter. 

Optional airflow cone helps in quick 
volume measurement, just install the
compatible airflow cone, meter will 
recognize the area for air volume 
calculations automatically. 
A hassle free way to take the value of 
air volume .
