2.4 Status LED indicator description

Figure 3 shows a diagram of the Met One 6000 particle counter. The remote airborne
particle counters use a laser diode light source and collection optics for particle detection.
The air quality of a clean room can be monitored by placing multiple particle counters at
specific locations in the room.
The Met One 6000 particle counter has three main components—the sensor, counting
electronics and communication electronics. Room air is pulled through the particle
counter by a vacuum source. The sensor detects the particles that enter the counter. The
counting electronics store the count data. The data is transferred to the central monitoring
software through the communication electronics and relevant communication protocols.
