Aerosol Inlet
The Aerosol Inlet is located on the front panel. The inlet consists of
a ¼” OD tube suitable for use with common tube fittings.
Permanent fittings with metal locking ferrules should be avoided
since this may inhibit removal of the front panel in the event service
is required. Aerosol inlet flows of 0.3 or 1.5 L/min can be set as
needed.
Particle Light
The particle light flashes each time a particle is detected. At high
particle counting levels (>10 counts per second) the light appears
continuously on.
Flash Memory Card Slot
The Model 3775 CPC provides storage of particle concentration data
using a standard flash memory card. A flash memory card is
included. Refer to
Using the Flash Memory Card in Chapter 4 for
more on how to use the Flash Memory Card. Technical information
is also found in
Chapter 7.
