Pitot tube anemometer + differential manometer; 5 pressure units
Fits duct air surveys where you need an Extech HD350 combining pitot-tube velocity/flow with differential pressure to ±5000 Pa class, ambient temperature, and USB PC logging.
Key advantages
- Velocity — 1–80 m/s (200–15,733 ft/min); ±3% rdg class
- Pressure — ±5000 Pa class; ±0.3% FS
- Flow — CFM/CMM with duct dimensions to 99,999 class
- Memory — 99 readings/mode (297); USB PC logging ~5500
- Kit — Pitot tube, dual hoses, USB software, 9 V, hard case
Typical applications
- HVAC duct velocity traverses.
- Differential pressure checks.
- Airflow volume with duct size entry.
Selection guide
- Pitot orientation — Facing flow
- Pressure units — Pa/psi/inH2O
- USB logging — Survey length
- Duct shape — Round vs rectangular
Common mistakes
- Meter not near-vertical during zero.
- Wrong pitot angle.
- Ignoring density/temperature context.
