Chapter 1 – About Particle Counting

1.1 How Do Particle Counters Work?

Laser particle counters use a laser diode light source and collection optics for particle detection. Particles scatter the light
from the laser diode beam in the direction of the collection optics. The collection optics focus the light onto a photo
diode that converts the bursts of light into electrical impulses. The pulse height is proportional to the particle size.
Impulses are counted and their intensity is measured for particle sizing. The results are then displayed digitally for the
specific size channel(s) and set measurement unit.

1.2 The Two ParticleScan Models

The six-channel ParticleScan handheld particle counters are available in two configurations:

 ParticleScan Pro

This model is designed for indoor air quality use, featuring a 0.025 cfm sampling rate.

The flow rate of 0.025 cfm of the ParticleScan Pro is more suitable for environments with normal to high particle
counts since the lower flow rate and smaller sampling diameter allow more accurate counting of elevated
particle concentrations.

 ParticleScan CR

This model is designed for cleanroom use, featuring a 0.1 cfm sampling rate and a HEPA filter for the exhaust air.

The higher flow rate of the ParticleScan CR permits statistically significant results even if the particle
concentration is low and the measurement time is short.

1.3 Data Logging Options

ParticleScan Pro and ParticleScan CR handheld counters allow the logging (recording) of measurement data onto the
ParticleScan’s internal memory from where it can be downloaded at a later time to a computer via the ParticleScan Utility
Software or a web browser.

When the ParticleScan is connected to a computer or network, measurement data can also be logged in real time to the
computer via the ParticleScan USB Utility Software.

In both cases, the data can be viewed and saved to a text file that can be easily opened and formatted in any common
spreadsheet program. Logged data can also be printed directly from the logging window to a printer.

A printout of particle counting results can be used as a record whenever documentation of room cleanliness is required,
as in Fed-Std-209E cleanroom certification. A permanent record is also useful when tracking the particle concentration
trend at a workstation or other remote location.

store and ship the ParticleScan in the carrying case.

2.2 Packing List

Open the two latches of the carrying case and inspect the kit for completeness. Also check visually for broken parts,
scratches, dents or other damage.

Your ParticleScan kit should consist of the following items:

• ParticleScan device (with

red protection cap on intake nozzle)

• Protective carrying case

• Isokinetic probe with tubing

• Power adaptor

• Purge filter with tubing

• Network cable (Ethernet, Cat. 5)

• Crossover adapter (Ethernet, Cat 5)

• USB cable

Chapter 3 – Getting to Know the ParticleScan

3.2 ParticleScan Features

sokinetic probe The isokinetic probe with the Tygon tube piece allows uniform low turbulence sampling of ambient air.

I

It is also necessary for proportional sampling of particles of all sizes.

Intake nozzle The intake nozzle is covered during shipping with a protective red plastic cap, which is designed to keep

mall objects from entering into the sampling chamber. The cap must be removed prior to taking a sample to prevent

s
possible damage to the internal pump.

Display When the device is off and not connected to the charger, the display will also be off. If the device is off and
connected to the charger, it will show [charging] or [charged]. When the unit is sampling, the particle concentration
measured will be displayed. The displayed concentration can be shown for one particle size range at a time (see Particle
Size Indicators). When the Menu key is pressed, the display will show the user settings.

Particle Size Indicators The particle size indicators show which particle size range is currently displayed. When the Alarm
is set and the set particle concentration threshold is exceeded, the appropriate particle size indicator will flash and a beep
will sound.

Cumulative Count Ranges There are six cumulative size channels to select from: ≥0.3 / ≥0.5 / ≥0.7 / ≥1.0 / ≥2.0 / ≥5.0
microns. When a cumulative size channel is selected, the ParticleScan will count particles which are equal to and larger
than the selected size channel.

Differential Count Ranges There are five differential size channels to select from: 0.3–0.5 / 0.5–0.7 / 0.7–1.0 / 1.0–2.0 /

2.0–5.0 microns. When a differential size channel is selected, the ParticleScan will count the particles whose size lies

between the selected two size channels.

Data Log Indicator This indicator lights up when data logging has been turned on. Whenever a measurement is taken, it
will be logged to the ParticleScan’s internal memory.

Timer On Indicator This indicator lights up when the auto timer is actively set. The Auto Timer is a feature that allows the
ParticleScan to take automatic measurements based on a timer schedule. The Auto Timer schedule is set via the
ParticleScan USB Utility Software or the web browser interface.

Low Battery Indicator When the battery is running low, both the Data Log Indicator and the Timer On Indicator will
flash. The unit can operate for another 5–10 minutes from the time the Low Battery Indicator comes on.

ON/OFF Key Press and hold for 2 seconds to turn the device on or off.

SAMPLE Key Press once when the device is on to start a measurement. Press again to stop a measurement.

UP/DOWN Keys Use during a measurement to select size channel displayed. It is also used to change a menu setting.

MENU Key Press 1 to 14 times to display one of 14 user menus.

ENTER Key Press and hold for 2 seconds when in a menu to make a menu item changeable. Press once in certain menus

to progress. Press and hold for 2 seconds to save changes in a menu.

Chapter 4 – Taking Measurements with the ParticleScan

4.1 Preparing the ParticleScan for Use

To prepare your ParticleScan for use, simply follow these steps:

1. Remove the red protective cap from the intake nozzle.

2. Take the isokinetic probe and attach it with the tubing end to the intake nozzle.

4.2 Switching the ParticleScan On and Off

1. To switch the ParticleScan on, press and hold down the ON/OFF key for 2 seconds. When the device is turned on, it
will sound a short beep and show [STANDBY] on the display.

2. To turn off the device, press and hold down the ON/OFF key for 2 seconds. When the ParticleScan turns off, it will

sound a short beep and the display will extinguish or show [Charging] when it is connected to the power adapter.

4.3 Sampling Particles

1. To take a measurement, turn the ParticleScan on and press the SAMPLE key. The display will count down while the
pump gathers the first air sample and then displays the first measurement. There will be a delay of a few seconds
until the countdown starts, during which the ParticleScan performs a routine check. The number in the display
represents the number of particles calculated to be present per cubic foot, liter or cubic meter (1000 liters) of air,
depending on the concentration unit selected (see Chapter 5.5).

2. The display of the ParticleScan will update in regular intervals, as selected in the Sample Time Menu. The default
setting is 6 seconds (see Chapter 5.6).

3. To stop taking measurements, press the SAMPLE key once. The last measurement result is now frozen on the display.

4.4 Taking Samples at Different Size Channels

The ParticleScan features six size channels which allows the user to take cumulative counts for six different particle size
ranges and differential counts for five different size ranges.

1. When the ParticleScan is first switched on, it will display the particle concentration per cubic foot (cu. ft.) of air for
the default Cumulative Count Range (i.e. ≥0.3µm).

2. To change the size channel to the next particle size range, simply press the UP key once. The Size Range Indicator
LED will shift from “≥0.3” to “≥0.5”.

3. Repeated pressing of the UP key will scroll through all the different size ranges, first the Cumulative Count Ranges,
then the Differential Count Ranges. To reach the required count range, simply scroll through all the count ranges
until the desired Particle Size Indicator is lit.
