TSI / Airflow PVM series

Hover to zoom

The TSI Airflow PVM610 and PVM620 micromanometers are easy to use, hand held digital instruments for fast, accurate and reliable pressure measurements.

Ideal applications include HVAC commissioning and troubleshooting, testing and balancing, Pitot tube duct traverses, static pressure measurements and environmental air flow testing.

The PVM620 has the capability of calculating volumetric flow rate in ducts from the velocity and user input of duct size and shape. It can also record data points in duct traverse using a sampling function, data log with time and date stamp and programmable K factors.
