PVM620
The Airflow PVM620 is a rugged, compact, comprehensive Micromanometer
that measures pressure, and calculates velocity and volumetric flow
rate. It can be used with Pitot tubes to measure velocity and then
calculate flow rates with user–input duct size and shape.
Premium features make it ideal for HVAC commissioning and troubleshooting,
environmental safeguards, process control and system balancing.
