Manometer
Model EBT720
The EBT720 is one of the most advanced, versatile, and easy to
use manometers on the market today. Auto-zeroing allows you
to make measurements throughout the day. The velocity matrix
accessory is useful in measuring face velocity through filters,
coils, and other specialized spaces.
Features and Benefits
• Accurately measures pressure, velocity (Pitot), and flow
• Large, easy to read display
• Data logging and downloading software included
• Automatic density correction
Rugged. Reliable. Professional.
EBT Balometer®Capture Hood
Model EBT721
The EBT721 Balomter®Capture Hood is a multipurpose
electronic air balancing instrument for reading air volume flow at
diffusers and grilles. It is ideally suited for commissioning agents,
test and balance contractors, facilities managers, health and
safety specialists, and ventilation installers. This light weight,
ergonomically designed kit saves time and money while helping
to create a healthy and energy efficient environment.

Optional Accessories Description / Part Number
Airflow Probe 800187
18” (46 cm) straight probe that can
be used to perform a duct traverse
and to measure face velocity
measurements in applications such
as chemical fume hoods, HEPA
filters, or other laminar flow devices.
Ideal for small diameter ductwork.
Velocity Matrix 801090
Used to measure face velocities of
HEPA filters, chemical fume hoods,
laminar flow benches, filter banks,
kitchen exhausts, and other
applications where a large surface
area needs to be measured. The 16
point grid covers one square foot
area and averages the air velocity
while minimizing the affects of
turbulence to produce a
stable reading.
Temperature Probe 800218
Telescopic probe extends from 9 to
40.5 inches (230 to 1030 mm) and
can be inserted into a standard
5/16 in. (8 mm) diameter hole
typically used for pitot traverses.
Temperature and Humidity Probe
800219
Telescopic probe extends from 9 to
39 inches (230 to 990 mm) and is
ideal for measuring inside of duct
work before and after a coil. Probe
can be inserted into a standard
5/16 in. (8 mm) diameter hole
typically used for pitot traverses and
can be used to calculate wet bulb
and dewpoint temperatures.
