BAPI Duct Averaging Units feature closed cell foam
to seal the probe insertion hole and absorb vibration.
Mounting tabs allow for easy installation directly to the
wall of the duct. All units have etched Teon leadwires and
encapsulated sensors to create a watertight package that
can perform under real world conditions.

Averaging probes should be used wherever there is a
chance for stratied layers of hot and cold air. Averaging
probes are made of bendable aluminum tubing and
measure temperature along their entire length. Nylon tie
straps are provided for mounting.

Duct Averaging Units come standard with a 2”x4” steel
J-Box but are also available with No Box, a BAPI-Box 4 or
three watertight enclosures: Weatherproof, BAPI-Box or
BAPI-Box 2. BAPI also offers optional liquid-tight ttings.
