Particle Counter
Fluke 983 Particle Counter
Troubleshoot and maintain
indoor air quality.
The new Fluke 983 Particle Counter, the preferred choice for HVAC and IAQ professionals,
measures temperature and relative humidity as
well as particle size. With expanded data

the Fluke 983 allows users to run more tests
quickly, with less time spent cycling through
screens to obtain data. The Fluke 983 is lightweight and easy to use in any position, with a
comfortable hand strap and rugged holster.
Use it to:

Quick Tips
Particle counts
Particle counts vary according
to a number of factors such
as location, time of year, and
occupants. When taking particle counts, always establish
an outside baseline reading to
compare indoor particle levels
against. Ideally, indoor particle
levels will be less then outdoor
levels.
Filter bypass
When testing for filter bypass,
take particle counts before
and after sealing the edges of
the filter with duct tape. This
will provide an indication of
how much particulate matter is
bypassing the filter due to poor
fitment or compromised sealing
surfaces.

Summary of cleanroom classification standards
Cleanroom particle concentrations
The above table presents airborne
particle limits for cleanroom applications per Federal Std 209E and ISO
14644 standards. The number of
particles per cubic meter represent the
maximum concentration limits for particles equal to and larger than the size
tested for. For example, an ISO class
5 cleanroom certified at 0.3 microns
should have no more than 10,200
particles 0.3 microns and larger. There
are other requirements regarding
sample volumes, locations and procedures that must be adhered to. Refer to
the applicable cleanroom standard for
more information.

Growing your business
through indoor air quality
particulate profiling
You’ve probably heard mold referred to
as the “new asbestos”
for HVAC/R.
Concern about
mold and its health
effects is driving consumers to
have their indoor
air quality (IAQ)
situation assessed
and, if necessary,
repaired.
If you’re the
contractor they
call, keep in mind
that mold isn’t the
only issue to consider when assessing the IAQ of a commercial building
or residence. Many different kinds of
particulates in a work or living environment can cause Sick Building Syndrome
and aggravate allergy and respiratory
conditions. Read a detailed application

Quick Tips
Frequent Calibration is Key
Frequent calibration of gas
sensors is key to maintaining
the accuracy and performance
of the device. Both CO2 and
CO sensors can exhibit tendencies to drift over time due to
environmental factors such as
temperature, humidity, and
pressure.
Fluke recommends monthly
calibration of the CO sensor,
and an annual calibration for
CO2 for optimum performance.

Application Note
Measuring air velocity with
the Fluke 975 AirMeter:
Using the velocity probe
Fro m t h e F lu k e D ig i ta l L i br ar y @ w ww .f l uk e .c o m/ l ib ra r y
Air velocity is a key parameter in evaluating airflow system performance. As part of basic testing, adjusting
and balancing of HVAC air distribution systems, most
HVAC technicians now use an anemometer to measure air velocity at grilles-registers-diffusers, within a
duct, or in open spaces.
Anemometers are typically very accurate tools,
especially at low velocities, but they must compensate
for air temperature, absolute pressure, and ambient
absolute pressure. The Fluke 975 AirMeter tool has an
accessory velocity probe that uses a thermal anemometer to measure air velocity. A temperature sensor in
the probe tip compensates for air temperature, a sensor in the meter reads absolute pressure, and ambient
absolute pressure is determined upon meter initialization. For users who prefer to calculate their own compensation factors, the meter will also display air velocity
or volume at standard conditions.
This application note describes how to take accurate
air volume measurements within a duct, air measurements at grilles-registers-diffusers, and other locations.
Air volumes within a duct
The ultimate goal of any duct
system is to move the required
air volume, while keeping all
other factors within acceptable
limits, and to deliver it in quantities and patterns that serve the
intended purpose: heating, cooling, ventilating, exhausting, mixing, humidifying, dehumidifying,
or otherwise conditioning the air
within a space. Velocity within
a duct is determined not only
by application, but also by how
the duct is designed. Key design
factors include: The level of
available static pressure that can
be overcome by the fan due to
friction losses and pressure drops
of devices within the air stream;
the cost of duct work; the space
available for duct work; and
acceptable noise levels.
To determine the air volume
delivered to all downstream terminal devices, technicians use a
duct traverse. Duct traverses can
determine air volume in any duct
by multiplying average velocity
readings by the inside area of
the duct. Traverses in main ducts
measure total system air volume,
which is critical to HVAC system
performance, efficiency, and even
life expectancy. The difference
in air volumes between the main
supply duct traverse and the
main return duct traverse results
in outdoor air volume. A traverse
in run-outs is the most accurate
way to determine the air volume
delivered by the terminal device
(grille-register-diffuser). A traverse in exhaust ducts reveals
exhaust air volume.

Air quality test
instruments must
deliver accurate
and verifiable performance, both to
ensure precise and
reliable air quality
diagnosis, and to
provide credible
answers if results

challenged. The
air quality professional’s reputation
depends on the quality and performance of the test tools in use, as well
as on their understanding of instrument

Quick Tips
How HVAC airflow impacts
operating costs
Dirty coils, fans, and filters
will increase static pressure
by reducing airflow, causing HVAC equipment to work
harder to meet occupant loads
and increasing energy costs.
With HVAC energy costs often
comprising over 50 % of
the total energy bill, tighter
monitoring and control of
HVAC airflow can have a direct
impact on the bottom line.
In a study1 on coil clean-
•
ing and energy savings in
a New York City high rise,
pressure monitoring and
visual inspection led to
restoration of the coils and
components. The restoration resulted in a 14 %
decrease in pressure drop
across the coils, a 25 %
increase in the coil’s thermal efficiency, and energy
savings of up to $40,000 in
the first year.
EPA studies2 show that a 15
•
cfm airflow differential can
impact annual HVAC energy
costs by up to 8 % depending upon the HVAC system
and variations in climate.

How many people are unintentionally poisoned by CO?
Every year, over 200 people in the
United States die from CO produced
by fuel-burning appliances (furnaces, ranges, water heaters, room
heaters). Others die from CO produced while burning charcoal inside
a home, garage, vehicle or tent. Still
others die from CO produced by cars
left running in attached garages.
Several thousand people go to hospital emergency rooms for treatment
for CO poisoning.

What is the permissible
exposure to CO?

Quick Tips
Duct temperatures
Use the Fluke 971 and an infrared thermometer to monitor duct
temperatures at the register.
Easily calculate dewpoint with
the Fluke 971, then compare it
to register temperatures to see
if they fall below the dewpoint.
Use an infrared thermometer
in this application as a general
indicator only. Many factors
come into play when taking IR
measurments, such as emissivity and spot-to-distance ratio.
Lower temperatures can lead to
condensation forming on ductwork. If uninsulated, moisture
can fall onto ceiling materials
and cause potential mold issues
and water damage.
Did you know?
Studies indicate that productivity
can increase anywhere from
0.5 % to 5 % given a comfortable
work environment. Use the Fluke
971 to monitor and maintain
comfortable conditions for your
customers—and demonstrate the
effectiveness of your repairs.
