General information
2.1.3 Class 1 LASER
A Class 1 LASER is installed in this instrument. Class 1 LASERS are products where the
radiant power of the LASER beam accessible (the accessible emission) is always below
the Maximum Permissible Exposure value. Therefore, for Class 1 LASERS the output
power is below the level at which it is believed eye damage will occur. Exposure to the
beam of a Class 1 LASER will not result in eye injury. Class 1 LASERS may therefore be
considered safe. However, Class 1 LASER products may contain LASER systems of a
higher Class but there are adequate engineering control measures to ensure that access
to the beam is not reasonably likely. This Class 1 Laser product complies with 21 CFR
Chapter 1, subchapter J. It is evaluated and tested in accordance with EN 61010-1,
Safety Requirements for Electrical Equipment for Measurement and Control and
Laboratory Use and IEC/EN 60825-1, Safety of Laser Products.
2.2 Configuration options
Figure 2 shows the part number configurations for the Met One 6000 particle counter.
This symbol indicates a laser device is used in the equipment.
This symbol indicated the presence of devices sensitive to Electro-static Discharge (ESD) and indicated that care
must be taken to prevent damage with the equipment.
This symbol identifies the location of a fuse or current limiting device.
This symbol indicates that the instrument contains a Class 1 LASER device.

General information
2.3 General product information
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.
2.4 Status LED indicator description
The particle counter has a multi-color LED indicator (Figure 3) that indicates the status of
the system. The colors indicate normal, alarm, alert or failure (refer to Table 1). The limits
that activate the indicator can be changed using the central monitoring software or the
setup utility (section 4.1.2 on page 30).

General information
Important Note: A yellow LED can be activated from the central monitoring software with
ModBus protocol to flash for count alert. The yellow LED cannot be activated with FX
protocol. If not activated by the software, the yellow LED will only turn on during startup
initialization.
For a description of the Ethernet LED indicators, refer to section 4.2.2.2 on page 36. For
a description of the Wireless LED indicators, refer to section 4.3.1.5 on page 40.
2.5 Theory of operation
The sensor in the Met One 6000 air particle counter contains a laser diode light source
that illuminates an area called the view volume with intense light. Particles in the sample
pass through the view volume and scatter the laser light, which is then collected through
the collection optics and focused onto a photodiode. The intensity of scattered light varies
depending on the size of the particle. The photodiode detects and converts the light
signal to electrical pulses, the magnitude of which is proportional to the particle size. The
information processed by the on-board controller electronics are then communicated to
the central monitoring system through the communication electronics.
The pulses are counted and measured by electronics on a circuit board containing
counting operations circuitry. Comparators are used to measure pulse height and sort the
signals into channels according to size. Counting circuits count the pulses in each
channel. The results indicate the particle counts for each size channel.
Calculations, if required by the operator, are performed and the data is available to the
I/O circuits for the facility monitoring system software through suitable communication
protocol or for peripheral devices. The firmware that controls counter operations is stored
in flash memory. The counting operations circuitry can also process external analog
signals from environmental probes when used.
Additional circuitry provides device controls for the sample flow and external accessories.
Power regulation and distribution circuits control the proper levels and internal application
of DC voltages.
Isokinetic sampling probes
The isokinetic sampling probe is designed for accurate sampling in laminar flow
environments. The velocity of air in the probe is close to that of a typical vertical or
horizontal laminar flow environment such as a clean room or clean hood. The probe will
match the vertical (or horizontal) flow speed of the air in order to collect representative
samples of the cleanroom laminar flow for the particle counter. Refer to Figure 4 for a
comparison of sampling with and without the isokinetic probe.
