CHAPTER 2

Photometer Overview

Instrument Description

The 2i is a forward light-scattering, linear digital
photometer. It operates on 100 to 240 Volts, 50 or 60
Hz, adjusting automatically. It’s most basic function is
to sample air or other gases and report the mass
concentration of particulates in the sample. The
primary application for the 2i is integrity/leak testing of
HEPA/ULPA filtration systems.

The 2i is a compact and lightweight instrument. The
instrument case is constructed of rugged die cast
aluminum. The pressure-sensitive keypad and large,
bright LCD display and indicators provide ease of
operation and readability. The auto-ranging and one­step zeroing features assure the accuracy of all
readings.

Using the 2i is extremely intuitive through the use of a
basic menu structure. Operation of the instrument is
simple and straight forward. Use of the fully
compatible iProbe affords full unit control from the
scanning probe. The 2i provides easy access to real­time results via USB or optional printer, while
remaining versatile enough to accommodate special
testing needs that have become commonplace in
today’s filter testing industry.

When all of these elements come together as they
have in the 2i, the testing process ceases to be a
training intensive exercise and becomes a “set and
forget” secondary routine performed as part of the
daily work requirements in clean room testing.

16 Aerosol Photometer - 2i 1800224 H.1

Filter Leak Testing: The Most Common
Application

The most common application of the Aerosol
Photometer 2i is to detect leaks in high efficiency
filtration systems (HEPA & ULPA). To validate the
integrity of a filtration system, a known challenge
agent consisting of an airborne test aerosol is
generated and introduced upstream of the filter. The
challenge agent provides particulate matter upstream
of the filter to allow measurements downstream of the
filter.

The test aerosol is introduced into the upstream side
of the filter(s) as far from the filters as is practical to
insure adequate mixing. Ideally, a distance of 10 duct
diameters upstream is considered the minimum. A
sample of the aerosol-air mixture should be taken
from the upstream side, close to the center of the
filter/filter bank. This sample is used to establish a
100% base line for the upstream concentration. The
2i is adjusted as described in the Operating Section to
set the 100% reading and the stray light is adjusted
automatically. The stray light adjustment
compensates for light reflection off internal surfaces of
the scattering chamber. After these adjustments have
been made, the 2i instrument is ready to check for
filter leaks/integrity downstream.

The filter test is performed with the use of the
scanning probe. The filter and the perimeter of the
filter pack should be scanned by passing the probe in
slightly overlapping strokes so the entire area of the
filter is sampled. The end of the probe should be held
one inch from the filter surface. Separate passes
should be made around the entire periphery of the
filter, along the bond between the filter pack and the
frame, and around the seal of the filter. Readings on
the meter will indicate percent of penetration.

The display indicates the percent of leakage through
or around the filter. The iProbe is supplied with the
industry standard rectangular, blue isokinetic nozzle.
This nozzle is used for fast scanning and is accepted
by many standards, including NSF 49-2008.

17 Aerosol Photometer - 2i 1800224 H.1

Other optional probes are available, a round, black 1
inch (25 mm) in diameter nozzle, which complies with
NSF (National Sanitation Foundation) Standard 49­1992, and a round, red, isokinetic nozzle. The
isokinetic nozzles are designed for media face
velocities of 90 +/- 20 feet per minute (fpm) when
using a 1 cfm (28.3 L/min) sample rate.

How the Photometer Operates

Theory of Operation

When air or gas is drawn through the instrument,
particulate matter in the sample passes through the
focal point of the scattering chamber. Particles
scatter light which is detected by the photomultiplier
tube, which converts the light into an electrical signal.
The signal is amplified and digitized, then analyzed by
a microprocessor to determine the intensity of the
light scattered by the signal. This signal is then
compared to a known reference signal to provide an
output that is normalized to the reference response.

A photometer is ideally suited to detect particulate
matter in air or gas, reporting the mass concentration
encountered on the unit display. Particles from less
than 0.1 micron to approximately 600 microns can be
readily detected by the 2i. Since the photometer
reports concentration of particulate matter, many
applications are possible.

18 Aerosol Photometer - 2i 1800224 H.1

Sampling System

A vacuum pump in conjunction with a flow meter,
onboard sensors and closed feedback loop provides a
constant volumetric sample flow rate of 1 cfm (28.3
liters per minute). The 2i uses an oil-free, dual head,
diaphragm pump with a direct-coupled DC motor.

Solenoid actuated valving directs the airflow through
the sampling system to the scattering chamber from
three possible sources. The CLEAR position directs
particle free air from an internal 0 REFERENCE filter
to the scattering chamber for zeroing the instrument.
The UPSTREAM position permits sampling of the air
above the filter being challenged, and the
DOWNSTREAM position permits sampling of the air
that penetrates the filter.

Light Scattering Chamber (LSC)

The scattering chamber is not only an integral part of
the sampling system; it is a major component in itself.
The scattering chamber is a complex electro-optical
unit that consists of a pair of hollow cones connected
at the apexes. A pair of collimating lenses first
straightens the light emerging from the light source,
and then focuses it at the center of the sampling
cone. An aperture forms a dark cone around the
photomultiplier, preventing light from arriving directly
on the photomultiplier. A condensing lens opposite
the LED source focuses light scattered into this dark
cone onto the photomultiplier tube.

Capabilities

The Aerosol Photometer 2i will measure percentage
leakage or absolute aerosol concentration. By using
a 100% baseline of 100 micrograms per liter of
aerosol, it is possible to directly read the
concentrations of aerosols.

Note

Before attempting to operate this unit, become familiar
with the features and functions.

Input / Output features

Alarms:

The 2i, when used in conjunction with the iProbe,
provides the user three sensory alarms: audible,
visual, and vibratory. When a reading exceeds the
user selected alarm point the display will turn red, a
tone will sound, and the iProbe will vibrate, if enabled.

19 Aerosol Photometer - 2i 1800224 H.1

Data Output:

Leakage data is sent out the unit’s USB port. This
data may be logged using contemporary data
acquisition software in real-time. Multiple types of
data formatting are available to satisfy a wide range of
applications (see “Reporting Modes” page 34 for more
details). A “Hard Copy” of the data can also be printed
using the optional printer accessory when “Summary”
reporting mode is selected.

Utility Requirements

Power

The 2i is equipped with a “Universal AC” power
supply capable of handling 100 to 240 VAC, 50 or 60
Hz. A line power conditioner and surge protector is
recommended.

Ambient Air Conditions

While the instrument was design to be operated
through a wide range of environmental conditions, we
recommend its use in a controlled environment where
the temperature is between 5°C and 50°C (41°F to
122°F Fahrenheit) and the relative humidity is
between 5% and 95% non-condensing.

Note

A dedicated power line is recommended for stable
machine operation.

The sampling ports connect the instrument to either
the scanning probe or 12 feet of clear tubing. They
are quick-connect type connectors and are
removable.

Each port contains a lint trap that should be cleaned
periodically to prevent clogging (see “Maintaining the
Photometer” page 62 for the procedure).

CHAPTER 5

Operating the 2i: Basic Operation

Before You Begin

1) Attach the supplied power cord and connect to an
appropriately rated electrical outlet. 110V @ 10
amps or 220V @ 5 amps.

2) Check the cleanliness of the upstream and
downstream port lint traps. They should be free of
fibers and debris.

3) Connect the iProbe electrical connector and
sampling line to the main unit if desired.

4) Connect the printer accessory or data acquisition
system if desired.

5) Enable operational power by placing the power
ON/OFF switch located on the entry module in the
‘ON’ position.

Note – User Manual

Make sure that the operator has been properly trained to
use the instrument. At a minimum, he should have read
this User Manual.

31 Aerosol Photometer - 2i 1800224 H.1

Step 1 Power On

Press the power button located at the lower right of
the front panel.

Step 2 Initialization

When the unit is powered on, it undergoes an
initialization cycle during in which it polls the system
for available sensors and verifies communication with
those sensors. The instrument will also regulate the
sample flow and once it reaches 28.3 ALPM the
initialization phase is complete.

Note

Other information available on the screen is the unit serial
number, software revision, machine identification number
and the total operating hours. See “Software Description”
page 41 for details.

Step 3 Establishing Zero Level

After initializing, the unit will automatically proceed
with establishing the zero level. This process takes
approximately 10 seconds. If the unit cannot
establish a zero, the operator will be prompted to retry
up to three times. The operator should press the Yes
button to retry or the No button to shut down the

instrument. The operator will have to press the Ok
button to shut down the instrument if the zero level
cannot be established at the last attempt.

Step 4 Main Menu

Once the zero level is established, the instrument will
display the main menu. The operator can then choose
to change parameters, such as the reporting function,
date and time, or the alarm settings. He must then
decide the method he wants to use to set the 100%
reference for the instrument.

Step 5 Selecting an Aerosol

Before proceeding with setting up the 100% it is good
practice to verify that the correct reagent is selected.

Note

The instrument saves the last reagent selected in battery
backed memory.

Step 6 Choosing a Setup Method

32 Aerosol Photometer - 2i 1800224 H.1

a Set 100% to Upstream Concentration

The instrument will attempt to establish its
reference baseline to the aerosol introduced in
the upstream aerosol port. If it is successful, an
estimate of the aerosol concentration, relative
to the selected internal reference reagent, and
stability will be communicated to the user.

Note

Selecting HIGH as the internal reference reagent during
this step allows sampling of upstream aerosol
concentrations up to 600-ug/l for brief periods. This
method is useful for identifying and correcting an over­challenge condition.

b Set Internal Reference

The instrument will set its reference baseline
and internal gain based upon settings stored
during factory calibration for the selected
aerosol reagent.

c Use Previous 100% Settings

The instrument will reset its reference and
internal gain setup to the prior settings.

After successfully setting up the 100% reference, the
instrument will automatically display the running mode
screen and switch the sampling valve to the
downstream aerosol port.

Step 7 Performing Leak Testing

The unit is now ready to perform leak testing or
aerosol monitoring. To return to the main menu select
the Home Menu key and press the Enter button (see
“CHAPTER 6 Software Reference” page 41 for a full
software description).

Note

If there is a concern that the zero baseline may have
drifted, the operator may re-zero the instrument at any
time by accessing the option in the main menu.

33 Aerosol Photometer - 2i 1800224 H.1

Reporting Modes

Summary Mode

The summary reporting mode was implemented with
certifiers doing in-situ validation of high efficiency
filtration systems (HEPA & ULPA) in mind. It provides
a summary of each filter tested on the USB port and,
if connected, the optional thermal printer. This feature
is similar to that of a particle counter.

When this reporting mode is selected, the
operator has the opportunity to enter a
location for the testing he is about to perform

by pressing the keyboard function key. This field is
automatically reset at the end of the test to avoid
unintended duplication of locations and should be
repopulated prior to subsequent testing. Remember

to select the enter/return key to save the entered
information before selecting EXIT.

To start the reporting, the operator
should press the play/pause function

key. The header will be sent out to the
ports and the acquisition of data sets will be initiated.
The button LED lights up green and the data transmit
icon is displayed ( ). A data set is sent every time the
operator presses the play/pause function key to
pause the test or at the conclusion of the test. When
the test is paused, the play/pause button LED lights
up yellow and the data transmit icon changes to
indicate the new status ( ). The maximum
penetration value is reset when the operator presses
the play/pause button to resume the test, allowing
the report to show all leaks present during the filter
scan.

34 Aerosol Photometer - 2i 1800224 H.1

Note

If the probe is disconnected when the instrument is in play
or pause, it will not synchronize with the base until the
stop button is pressed.

Note

If a leak is detected while scanning, the operator should
press the play/pause function key to pause the reporting
and acquisition of data while he fixes the leak. Pressing the
play/pause function key will also stop the effective
scanning time until it is pressed again.

Aerosol Noise Suppression

Note

The Downstream Aerosol Noise Suppression (DANS) is
not available when the iProbe is connected to the
instrument. This prevents the user from accidentally
skewing results by suppressing actual readings in the
downstream mode.

Upstream Aerosol Noise Suppression (UANS)

The Upstream Aerosol Noise Suppression mode is
selectable by the operator when using the upstream
port during measurement, not while setting 100%.
When poor upstream mixing makes the measurement
of the upstream concentration difficult, the noise
suppression should dampen these variations.

An icon indicates when UANS is ON. The default
condition is ON. Power cycling the unit will restore the
instrument UANS mode to the default condition, ON.

Maintaining the Photometer

Definitions and Features

The 2i Aerosol Photometer is a sturdy, solid-state
electronic instrument designed to hold up under
extended field use. The only moving parts are the
vacuum pump, the selector valve and the ventilating
fan at the rear of the chassis. Field level maintenance
is limited to replacement of the fuses and cleaning of
the lint screens. Procedures for these operations are
contained in this section.

Note

The internal electronics are not user serviceable. Any
electronic problems must be analyzed and repaired at an
authorized service center.

Intervals are defined as follow:
Day 8 hours of operation
Week 40 hours of operation
Annual 2080 hours of operation

62 Aerosol Photometer - 2i 1800224 H.1

Recommended Scheduled Maintenance1

Daily

 Clean the aerosol ports screens. These are

located in the black circular aerosol port connector
on the front panel of the main unit.

 Remove any loose debris from the Scanning Probe

and front panel sampling ports.

Annually

For 115 V or
220 V

ATI Part Number 6400001
(5 X 20 mm, 2A, 250V, SLOW BLO)

Cleaning the Lint Screens

The aerosol port connectors on the main unit contain a
wire screen to prevent fibers and large particles from
being drawn into the photometer. If the screens
accumulate a significant amount of debris and become
partially clogged, it can interfere with the airflow and
affect the accuracy of the photometer and may put an
unnecessary strain on the vacuum pump.

Note

It is recommended that all screens be wiped clean with a
lint-free cloth before use each day.

If the screens are punctured, replace them
immediately. Spare nozzles and replacement scanning
probe components can be ordered from ATI (see
“APPENDIX E Maintenance and Spare Items” page

72).
