TSI Airflow PVM620 Micromanometers from Kenelec Scientific are hand held digital devices that measure pressure and then calculate velocity and volumetric flow rates. This unit can be also used with Pitot tubes to measure velocity and calculate flow rates with user-input duct size and shape.
PVM620 Micromanometers measure differential and static pressure ranging from -3735 to +3735 Pa. They record data points in duct traverse using sample function and data logging with time and date stamp. This model also includes LogDat2 downloading software and Programmable K factors.
These robust and compact devices make fast, accurate and reliable pressure measurements. Their features make them ideal for use in the following applications:
- HVAC commissioning and troubleshooting
- Testing and balancing
- Pitot tube duct traverses
- Static pressure measurements
- Environmental air flow testing
