• Multi-Function Display - view pressure, air velocity, or air flow plus temp. simultaneously
• Use one input to measure the gauge pressure of a single source
• Use both inputs to measure the differential pressure between two points
• Duct shape, parameter settings for airflow measurement are recalled when powered up
• Real-time Data Acquisition for viewing and storing readings directly on your PC

The Triplett Model DPR400 Airflow Meter/Pitot Tube Anemometer is a versatile instrument that simultaneously displays Pressure, Air Velocity, or Air Flow, along with Temperature. It offers the flexibility to use one input to measure the gauge pressure of a single source or both inputs to measure the differential pressure between two points. The instrument recalls duct shape and parameter settings for airflow measurement automatically at power-up and features a Zero display adjustment for all three modes.
