Digital Gauge
Figure 7: DM-32 digital gauge.
Model 340 use the DM32 gauge while Model 342 signifies the WiFi enabled gauge that works exactly the
same in every other respect.
The latest Retrotec Digital Gauge is included with all Retrotec DucTester systems. The gauge can be
combined with the Model 300 fan for automatic control to Set Pressure or Set Speed. The gauge is a
dual-channel manometer, which can automatically convert the measured Fan Pressure into a range of
useful results that meet every major testing standard in the world.
The gauge is also capable of taking a Baseline pressure reading, and automatically recalculating results,
in order to reflect this bias pressure. It can auto zero itself to ensure pressure readings do not drift away
from the true pressure value during a test. It is also capable of displaying results that are extrapolated
to any pressure.
For more information on configuring and using the DM-32, see the
DM-32 Operation Manual

Flex Duct
Retrotec's duct testing systems US340 and EU340 include a 10" diameter, 12' long flexible duct to
connect the fan to a register, or duct system. A durable plastic Flange on one end is taped to a register
or air handler, and connected to the Flex Duct to ensure a strong and simple seal. Velcro straps on
either end securely attach the Flex Duct to the Flange and fan inlet or outlet.
