ACI SPT-3.5" : Aluminum Static Pitot Tube, 4" (101.6 mm) Insertion Length
The SPT is an Aluminum Static Pressure (Aspiration) probe used to monitor the static pressure in an HVAC duct or equipment application. The static pressure probe 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, filter blockage, or reduced air flow with little or no static pressure in non-critical applications
