Extech HD350 Pitot Tube Anemometer and Differential Manometer

What is the Extech HD350 Pitot Tube Anemometer and Differential Manometer?

The Extech HD350 Pitot Tube Anemometer and Differential Manometer is a professional airflow and pressure measurement instrument designed for HVAC engineers and ventilation technicians working on duct systems, air handling units and commissioning tasks. Using a Pitot tube, it accurately measures air velocity, airflow volume and differential pressure, even in tight or hard-to-reach ducts where vane anemometers cannot be used.

With simultaneous display of pressure, airflow or air velocity and temperature, the HD350 supports efficient diagnostics and verification during installation, balancing and fault-finding. Its wide pressure range and multiple selectable units make it suitable for both commercial and industrial ventilation applications.

 

How does the Extech HD350 perform in everyday HVAC work?

The HD350 combines precision measurement with practical on-site features such as data storage, backlit display and USB connectivity. Engineers can quickly zero the instrument for accurate readings, log results for reporting and work confidently in low-light plant rooms or ceiling voids.
