2 Introduction
Overview This operating manual describes how to use the Lighthouse SOLAIR
1.0 CFM, Gen E portable particle counters, such as the SOLAIR 3100
and 5100 and the Boulder Counter.
The model number (except in the case of the Boulder Counter) signifies
the minimum particle size measured by the instrument. The number
“3100” indicates a 0.3 μm minimum channel size at 1.0 CFM. The
number “5100” indicates a 0.5 μm minimum channel size at 1.0 CFM.
The Boulder Counter, due to its large-particle counting ability starting
at 5.0 m, does not use a model number, per sè.
All models discussed in this manual have a color touchscreen, may
have the thermal printer option installed, may have the battery option
installed and can store up to 3000 records. The Boulder Counter is an
exception because it includes all of the features.
SOLAIR 3100 and 5100 instruments support up to eight particle-size
channels, four 4-20mA analog sensors, built-in thermal printer and a
rechargeable, removable Li-Ion battery. The Boulder Counter supports
only six particle-size channels.
Note:
For lists of the
standard channel sizes
available for each SOLAIR
model, see the SOLAIR
Specifications section in
this chapter.
All SOLAIR instruments contain a microprocessor that controls all of
the instruments’ functions. Count data is displayed in cumulative or
differential mode as raw data or normalized in particles per cubic foot
or per cubic meter.
SOLAIRs use the Extreme Life Laser Diode Technology for a laser life
span of greater than 20 years and collection optics for particle
detection. Particles are directed through the laser’s beam and scatter its
light. The collection optics collect and focus that light onto a photo
diode that converts it into electrical pulses. The pulse height is a
measure of particle size. Pulses are counted and their amplitude is
measured for particle sizing. Results are displayed as particle counts in
the specified size channel.
Utilizing a large touch screen interface, SOLAIR instruments are easy
to configure and operate.
