3.2.2 Experimenting AOT monitoring
Understanding by experimentation is important in aerosols studies.
Aerosols can be modeled using particles in water that behave similarly to those in
the air.
The use of water makes it possible to keep the particles in suspension longer, to
remain in a restricted area (aquarium) and does not require an enormous volume
(about seven in
3
). Finally, the experimenter can easily change the type of particle
to be observed..
Here is a montage that uses a high power LED lamp and a device that allows to
align the Calitoo with the lamp while leaving a space to place the mini aquarium
that contains the water :

Results of measurements with milk: The Angström coefficient (Alpha) is high,
indicating the presence of fine particles in majority.
Visually, the blue, green and red curves are spaced apart.
