2 Introduction
Overview This operating guide describes how to use the Lighthouse
HANDHELD 2016, 3016 and 5016 Airborne Particle Counters.
The HANDHELD 2016 has up to six particle-size channels starting at
0.2 microns with a flow of 0.1 CFM and a touch screen interface. The
HANDHELD 3016 has up to six particle-size channels starting at 0.3
microns and the HANDHELD 5016 has up to six channels starting at
0.5 microns. They are otherwise identical to the 2016 model. A
microprocessor controls all instrument functions. Count data is
displayed as cumulative or differential count.
The model number signifies the minimum particle size measured by the
instrument. The number “2016” indicates a 0.2μm minimum channel
size at 0.1 CFM with up to 6 channels. The number “3016” indicates a
0.3 μm minimum channel size at 0.1 CFM with up to 6 channels. The
number “5016” represents a 0.5μm minimum channel size at 0.1 CFM
with up to six channels.
The instrument uses a laser-diode light source and collection optics for
particle detection. Particles scatter light from the laser diode. The
collection optics collect and focus the light onto a photo diode that
converts the bursts of light 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.
