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.
Features
- Measures differential and static pressure from - 3735 to + 3735 Pa
- Calculate and display velocity when using an optional pitot tube (See separate section for a full range of pitot tubes)
Added features for the PVM620 model
- 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 logging with time and date stamp
- Includes LogDat2™ downloading software
- Programmable K factors
