Airflow Instruments PVM620 Micromanometer


The Airflow™ Instruments Micromanometer PVM620 is a rugged, compact, comprehensive micromanometer that measures pressure and calculates velocity or volumetric flow rate through assignment of suitable duct areas.
It is best suited for HVAC commissioning and troubleshooting, environmental safeguards, process control and system balancing.



  • Measures differential and static pressure from –3735 to +3735 Pa
  • Calculates and displays velocity when using a Pitot tube
  • Calculates volumetric flow rate in duct from velocity and user-input duct size and shape
  • Records data points in duct traverse using sampling function
  • Data logs up to 12,700 samples and 100 test IDs with time and date stamp
