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.

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.

Installation
3.3 Installation guidelines
Important Note: Stop the vacuum pump and put a cover on the sample inlet connection
before a cleaning or disinfecting cycle is started.
Refer to the following general guidelines during installation.
•If the room is washed down at regular intervals, installthe counter outside of the room.
Only the intake and vacuum tubes will go into the clean room. As an alternative, put
the particle counter in the clean room in a sealed box. Connect all tubes and cables to
the particle counter through the box.
•Put the vacuum pump in a central location. There must be sufficient vacuum for all
particle counters in the network.
•Make sure that the temperature in the installation area is not more than the specified
temperature for the particle counter (refer to Specifications on page 3). A high
temperature decreases the life of the electronic components and laser.
•Keep the distance between the particle counter and the sampling point to a minimum.
Make sure that the distance is not more than 3 m (10 ft).
•Make sure that the tubing does not bend and restrict the air flow (refer to section 3.4.2
on page 14).
•Follow the Sampling guidelines on page 17 to prevent sampling errors.
Vacuum system guidelines
Important Note: Put the vacuum pump in a central location. There must be sufficient
vacuum for all particle counters in the network.
•Capacity—a minimum vacuum capacity of 16 inches Hg (542 mbar) is necessary at
each particle counter. The vacuum is necessary to control the flow rate at each
particle counter.
•Distribution manifold—use a distribution manifold that will keep the vacuum loss to a
minimum. Typical materials used for vacuum distribution include brazed copper pipe,
schedule 80 PVC pipe or tubing such as Cobolite®.
•Distribution valves—use short tubing lengths to supply the vacuum from the
distribution manifold to the individual particle counters. Use a valve and a barb fitting
of the correct dimension at each location.
•Minimize piping loss—all junctions, elbows and the tubing length increase the vacuum
loss in a system. The loss increases as the distance from the vacuum source to the
counters and the number of junctions and elbows increase.
3.4 Mechanical installation
3.4.1 Installing the particle counter
Install the particle counter on a level surface or on a wall with one of these kits:
•DIN rail kit (included with counter)—use to quickly remove the counter from the wall.
•Terminal box kit (optional)—use to quickly disconnect the vacuum line and wires (refer
to Parts and accessories on page 47. The instructions are supplied with the kit.)
•Wall plate (optional)—use for permanent installation (refer to Parts and accessories
on page 47. The instructions are supplied with the kit.)
DIN rail installation
The DIN rail kit lets the user quickly attach and remove the counter from the wall.

14
Installation
Prerequisites:
DIN rail kit (refer to Parts and accessories on page 47). Kit contents:
•DIN rail section, approximately 6 in. length
•2 clips
•2 clip screws
Installation procedure:
Complete the following steps to install the particle counter with the DIN rail kit.
1. Attach the 2 clips to the counter with the supplied screws (Figure 7).
2. Attach the DIN rail to a wall with customer-supplied hardware. Make sure that the
flanges on the rail point away from the wall.
3. Align the clips on the counter with the top flange of the DIN rail and push to lock
in position.
Note: To remove the particle counter from the rail, lift the bottom of the counter.
3.4.2 Tubing installation
Use hooks or cable ties to hold the tubing and prevent a bend in the tubing. A bend in the
tubing can restrict the air flow and cause the following problems:
•A restriction on the sampling side can cause particles to collect on the inside of
the tubing. The particles will not be counted. The collected particles can release at
random, which will cause spikes in the count level.
•A restriction on the vacuum side will cause the vacuum to fall below specified
levels. The low vacuum can cause a flow alarm and low particle count.

Installation
Prerequisites:
•Sample tubing—Hytrel®Bevaline, Tygon®or equivalent
•Vacuum tubing—Hytrel Bevaline, Tygon or equivalent
•Tubing hooks or cable ties
Installation procedure:
Important Note: Do not connect the vacuum tube to the vacuum source until the room is
ready for sampling.
Complete the following steps to install the intake or vacuum tubing.
1. Cut the intake (sample) tubing to connect the counter to the sample probe. Keep the
tube length to a minimum. Make sure that the length is not more than 3 m (10 ft).
Note: A tube length that is longer than 3 meters can cause a loss of particles > 1 µm. If a longer
length is necessary, compare the results between a portable particle counter and the remote
particle counter. A lower result in the remote counter indicates a tube length that is too long.
2. Cut the vacuum tubing to connect the counter to the vacuum source. Keep the tube
length to a minimum.
3. Put a cover on the tube ends to make sure that unwanted material does not go in the
tubes during installation.
4. Support the tubing with hooks or cable ties at intervals that are not more than 4 feet
apart. Make sure that the tubing has a minimum bend radius of 4-inches (refer to
Figure 8).
5. Connect the intake tubing to the fitting on the top of the particle counter. Connect the
other end of the tubing to the isokinetic probe.
6. Connect the vacuum tubing to the fitting on the bottom (or side) of the counter. Do not
connect the other end to the vacuum until the room is ready for sampling.

Installation
3.4.3 Sample probe installation
The sample probe must be installed correctly to prevent contamination of the counter and
to get a representative sample of the area.
3.4.3.1 Sample probe kits
The following optional kits are available for installing the sampling probe. Refer to
Figure 9 and Parts and accessories on page 47 for order information.
•Direct mount—the probe is installed on a short piece of tubing directly on top of the
counter (Figure 6). Use this probe when the particle counter can be located where the
sample is collected. Use the direct mount probe to keep particle loss to a minimum.
•T-type wall bracket—the probe is installed in a wall bracket. The tubing is cut to
connect the probe to the counter.
•Vertical wall mount—the probe is connected to a stainless steel tube and bracket. Use
this probe for installation on equipment with stainless steel tubing. The probe can be
located where the sample is collected.
•Through-wall mount—the probe is connected to a stainless steel tube and wall
bracket. Use this probe to collect samples on the other side of a wall from the counter.
•Ceiling mount—the probe is connected to a stainless steel tube (J-hook or 90 degree)
and ceiling bracket. Use this probe to collect samples in the middle of a room or when
the particle counter is installed above the room.

Installation
3.4.3.2 Sample probe guidelines
The position of an isokinetic probe is very important for count accuracy. Refer to the
sampling guidelines and Figure 4 on page 9 before installation.
Sampling guidelines
•Keep the sample probe a minimum of 12 inches from loose materials, dust, liquids
and sprays.
•Keep the sample probe a minimum of 12 inches from potential contamination sources
such as an instrument exhaust fan.
•Laminar flow—install at least 1 sample probe per 25 sq. ft. of surface area.
•Turbulent flow—install at least 2 sample probes per clean room.
•Position the sampling probe to face the direction of flow (refer to Figure 4 on page 9).
•Powders will contaminate the sensor and cause incorrect results or a counter failure.
•Liquids will contaminate the internal optics of the sensor and change the calibration of
the counter. Liquids can be suspended in air in the form of oil droplets.
•The vapors from drying adhesives or other chemicals can permanently coat the
sensor optics or other internal parts.
•All types of smoke will contaminate the sensor.
•Vapors that contain corrosives will quickly cause permanent damage to the optics or
electronics of the counter.
3.5 Wiring safety information
When making any wiring connection to the instrument, obey the warnings and notes that
follow. Obey all warnings and notes in the installation sections. For more safety
information refer to section 2.1 on page 5.
Important Note: Always remove power to the instrument before an electrical connection
is made.
Electrostatic discharge (ESD) considerations
To keep hazards and ESD risks to a minimum, remove power to the instrument when a
maintenance procedure does not require power.
Internal electronic components can be damaged by static electricity. This damage can
cause degraded instrument performance or instrument failure.
To prevent ESD damage to the instrument, complete the following steps:
•Before touching an electronic component, discharge static electricity from the body.
Touch an earth-grounded metal surface such as the chassis of an instrument or a
metal conduit or pipe.
•To keep static build-up to a minimum, avoid excessive movement. Transport
static-sensitive components in anti-static containers or packaging.
•To discharge static electricity from the body and keep it discharged, wear a wrist strap
connected by a wire to earth ground.
•Handle all static-sensitive components in a static-safe area. If possible, use anti-static
floor pads and work bench pads.
