Aerosol Photometer
Aerosol Photometer - 2i 19
The scattering chamber is a complex electro-optical
unit that consists of a pair of hollow cones connected
at the apexes. A pair of collimating lenses first
straightens the light emerging from the light source,
and then focuses it at the center of the sampling
cone. An aperture forms a dark cone around the
photomultiplier, preventing light from arriving directly
on the photomultiplier. A condensing lens opposite
the LED source focuses light scattered into this dark
cone onto the photomultiplier tube.
Capabilities
The Aerosol Photometer 2i will measure percentage
leakage or absolute aerosol concentration.

with the features and functions.
Input / Output features
Alarms:
The 2i, when used in conjunction with the iProbe,
provides the user three sensory alarms: audible,
visual, and vibratory. When a reading exceeds the
user selected alarm point the display will turn red, a
tone will sound, and the iProbe will vibrate, if enabled.
Data Output:
Leakage data is sent out the unit’s USB port. This
data can be logged with contemporary data
acquisition software in real-time. Multiple types of
data formatting are available to satisfy a wide range of
applications (see “Reporting Modes” page 34 for more
details). Data can also be printed to hard copy using
the optional printer accessory when using the
summary mode.
