CEM DT-8920 PRESSURE & FLOW METER

DT-8920 is a Pressure and flow meter simultaneously with an easy-to-read, large, backlit LCD display. Measurement data is printed on site with minimum and maximum values. It can Monitor air pressure across key HVAC components and Promote good indoor air quality, which Ensure proper air flow balance and Maintain a comfortable environment.
Larger LCD display with backlight.
Relative time clock on MAX MIN and AVG provides a time reference for measurement.
Pressure, velocity or air flow measurement provides Zero Adjust.
Display pressure, Air velocity or air flow plus environment temperature simultaneously.
Easy to calculate the area of a rectangular or circular duct.
USB interface, USB to UART Bridge Controller..
