The CEM DT-8920 Pressure & Flow Meter uses a Pilot Tube to measures Air Velocity/Airflow in difficult-to-reach or tight locations where a vane anemometer won’t fit.
CEM DT-8920 Features:
- Simultaneous display of Pressure, Air Velocity or Air Flow plus Temperature
- ±0.7252psi range
- 5 selectable units of pressure measurement
- Large Backlit LCD Display
- Easy to Calculate the area of a rectangular or circular duct
- Max/Min/Avg. recording and Relative time stamp
- Data Hold and Auto power off functions
- Large LCD display with backlight
- Zero function for offset correction for measurement
- Store/Recall up to 99 readings in each mode
- USB port, includes software
- Conforms to CE, EMC, EN: 61326
