Safety information
This section gives instructions for promoting safe and proper handling of the Particle Counter.
Laser Safety
The Handheld Laser Particle Counter is a Class I laser- based instrument.
During normal operation, you will not be exposed to laser radiation.
Precaution should be taken to avoid exposure to hazardous radiation in the form of intense,
focused, invisible light.
Exposure to this light may cause blindness.
Take these precautions:
DO NOT remove any parts from the particle counter unless you are specifically told to do so in
this manual.
DO NOT remove the housing or covers. There are no user serviceable components inside the
housing.
DANGER
The use of controls, adjustments, or procedures other than those
specified in this manual may result in exposure to hazardous optical
radiation.
Precautions for power use
AC Adaptor
The AC adapter accommodates voltage of AC 100~240V and frequency of 50/60Hz.
Batteries
Use four AA Batteries.
DANGER
Driving voltage should be kept within specified range.
Failure to follow this instruction may cause electric
shock and instrument damage.
CAUTION
Do not start sampling when the instrument is connected to a personal
computer.
Failure to follow this instruction may cause
the instrument to work abnormally.

Getting Started
The Handheld Laser Particle Counter (particle counter) is a lightweight, handheld particle counter
with a TFT LCD display. It operates on battery orAC power. This model has a 0.1 CFM (2.83 L/min)
flow rate and counts in user-adjustable bin sizes of 0.3/0.5, 0.5/1.0/2.0/2.5 and 5 microns (channel
1 and 2 are selectable). Up to 8000 data sets can be stored and downloaded for analysis and
reporting using the utility included with the device.
Inlet nozzle:
User can replace the Inlet nozzle between the isokinetic inlet and the probe for tubing. The
isokinetic inlet is used for ambient air sampling. To use the isokinetic inlet, detach the red
cap from the inlet nozzle and attach the isokinetic probe. After all the samples are completed,
please detach the isokinetic inlet and put the red cap back before placing the unit into the
carrying case. If you are planning to use a tube for sampling, please contactAiry Technology
or your local distributor.
Zero filter
The zero filter cleans the sensor after your sampling at contaminated places. The zero filter
also checks whether the particle counter is counting electrical noises. To use the zero filter:
1. Detach the isokinetic inlet from the main unit
2. Connect the zero filter to the main unit using the tube (There is a tube in the plastic bag
containing the zero filter)
Key Pad
Inlet nozzle
LCD display
USB Port

3. Start sampling
4. Wait until the counter does not detect any particles
5. Stop sampling and detach the zero filter
If the counter keeps detecting particles after 1 minute of sampling, please contact Airy
Technology or your local distributor.
AC power, USB port, and USB cable
1. AC Power
When using AC power, must use the affiliated AC adapter, shown below.
