Differential Pressure, Airflow and Pitot Tube Meter - (DPR400)

The Triplett Model DPR400-NIST Airflow Meter/Pitot Tube Anemometer with Certificate of Traceability to N.I.S.T. can simultaneously display Pressure, Air Velocity, or Air Flow plus Temperature. Use one input to measure the gauge pressure of a single source. Use both inputs to measure the differential pressure between two points of a single source or between 2 sources revealing which input has the higher pressure and the difference between them. Measurements are viewed on the large backlit LCD display in 5 units of measure. Connect the included pitot tube to measure air velocity or air flow. Duct shape and parameter settings for airflow measurement are recalled at power up. There is a Zero display adjust for all three modes. Min/Max/AVG records highest, lowest and average readings with relative time stamp. Data Hold momentarily freezes the displayed reading for easy viewing. It features store/recall up to 99 readings in each mode. Stored readings can be downloaded via USB interface to yo
