Introduction and

The AeroTrak
®
Remote Airborne Particle Counter (particle counter) is a
compact sensor that is appropriate for use in multiple locations in a large
clean room or critical environment to continuously monitor a process. The
sensors are very simple compared to a typical particle counter. They
have no display (other than several LED indicators) and no pump (central
vacuum is used along with an integral critical orifice).
Sensor data and particle counter information is communicated to an
external device via 4-20 mA outputs and a digital contact. Oftentimes, this
data is sent to a data logging software, like TSI’s Facility Monitoring
Software.
The following table shows the remote particle counter models covered by
this manual.

*While these Remote Particle Counters have four size channels, only two analog outputs
are available to use at any one time.
