EXTECH HD350 - Pitot Tube + Anemometer Diff Manometer
Extech HD350 Pitot Tube Anemometer + Differential Manometer
The Extech HD350 combines a Pitot tube anemometer and differential manometer in a single rugged instrument, giving restoration and HVAC pros a fast, accurate read on air velocity, air flow, and differential pressure. Measure differential pressure in five selectable units and use the included Pitot tube and dual connection hoses to capture air velocity and air flow on the job.
Built for real-world fieldwork, the HD350 offers data hold, auto power off, a zero function, and manual record/recall of up to 99 readings. The built-in USB port and included software make it easy to transfer and log your data. Backed by ±1% full-scale accuracy on air velocity and ±0.3% full-scale accuracy on pressure, it delivers dependable measurements you can stand behind.
