Retrotec DM-2 Series Quick Start Manual

Retrotec DM-2 Series
2-Channel Digital Pressure
Revolutionary New Airflow Diagnostics
The on the fly display puts the operator in command of
virtually every parameter of interest to the door-fan
tester. The DM-2 represents a huge advance in
building and envelope diagnostic instrumentation.
USB Uplink allows the DM-2 Series Gauge to be connected to
a computer for Data Acquisition, Automatic Control or
remote data monitoring. Ask us about our software
development kit for Excel or Visual Basic.

DM-2 With Manual Speed Control
DM-2A Features Automatic Speed and
Pressure Control
Displayed on the fly or extrapolated to your desired
test pressure. No need to achieve an exact speed
to get perfect results!
Air-changes
without a
laptop!
Input the volume of your building and adjust the
fan to your desired test pressure. Can't reach your
test pressure – no problem – Use @-Pressure to
extrapolate to 50Pa, 25Pa, or any other pressure.
Permeability and Specific Leakage Rates (as per
EN13829 and TM23) can also be displayed in real
time, by simply entering either the floor or
envelope areas.
Automatic
Pressure
Control
The DM-2A offers onboard "Set-and-Forget" control
of house pressure and flow pressure. Save time
and effort by setting to 50Pa and let the DM-2A do
the rest. As you identify and seal leaks, the system
automatically adjusts the fan speed to hold the
desired house pressure.
Automatic Control requires a DM-2A and works with
all 2200, 3200 and DU220 Digital Fan Products.
