NSA-VPT
The VPT Series is an Aluminum Velocity Pressure or flow (Impact) probe used to sample the air flow in HVAC duct or equipment applications. The VPT should be mounted approximately 5 to 8 duct diameters downstream from elbows, obstructions, or large change in duct area to reduce the amount of turbulence that will affect your readings. Applications: Used to monitor fan operation and true air flow with varying amounts of static pressure in non-critical applications.
