Extech HD350
The Extech HD350 is a versatile instrument capable of measuring air velocity/flow, differential pressure, and temperature, ideal for ventilation, HVAC, ductwork, and inspection applications in hard-to-reach areas.
Key Features
- Simultaneous display of: pressure, air velocity or air volume plus temperature.
- Measures differential pressure in five selectable units (psi, mbar, inH₂O, mmH₂O, Pa).
- Air velocity range from approximately 1 m/s to 80 m/s (≈ 200-15 733 ft/min) plus volume flow up to 99 999 CFM/CMM.
- Large, illuminated LCD display with backlight for easy readability.
- Recording functions: Max/Min/Average values, Data Hold, Auto Power Off (can be turned off).
- USB port for connection to PC + supplied software/cable for data logging.
- Supplied with pitot tube (including two hoses of approximately 85 cm), 9 V battery, hard carrying case.
Applications
- Inspection of ventilation ducts, HVAC systems, air handling units and air outlets.
- Control air velocity and flow in tight or difficult-to-reach spaces where standard anemometers do not fit.
- Measurement of differential pressure in ventilation ducts or between rooms.
- Trend analysis or reporting via PC software thanks to the USB connection.
