The AeroTrak
®
Model 9303 Handheld Airborne Particle Counter (particle
counter) is a lightweight, handheld device with a backlit LCD display. It
operates on the included lithium-ion battery or AC power. This model has
a 0.1 CFM (2.83 L/min) flow rate and counts in user-adjustable bin sizes
of 0.3, 0.5/1.0/2.0/2.5, and 5 microns (center channel is selectable). Refer
to the Model 9303 Operation Manual (P/N 6002277) for device operation.
The AeroTrak
®
Models 7201/7301/7310/7501/7510 Remote Airborne
Particle Counters (particle counter) are compact sensors. They have no
display (other than several LED indicators) and no pump (central vacuum
is used along with an integral critical orifice). Refer to the AeroTrak
Remote Airborne Particle Counters, Models 7201/7301/7501/7310/7510
Operation and Service Manual (P/N 6002276) for device operation.
Refer to the Model 7301-P Operation Manual (P/N 6004433) for device
operation.
