Lighthouse Worldwide Solutions ApexZ Operators Manual
248083466-1 R3 11
Introduction
Overview
This operating manual introduces the Lighthouse ApexZ portable particle counters ApexZ3 and ApexZ50
and includes instructions for inspecting, installing, using and maintaining the instrument.
Description
The ApexZ portable particle counter comes standard with 6 particle-size channels (ApexZ3: 0.3, 0.5, 1.0,
3.0, 5.0, 10.0 microns), (ApexZ50: 0.5, 0.7, 1.0, 3.0, 5.0, 10.0 microns) and a flow rate of (ApexZ3: 1.0
CFM), (ApexZ50: 100LPM). The instrument uses a LASER diode light source and LASER beam shaping
optics to illuminate a cross section of the air flow path. As particles move along this path, they cross the
LASER beam and scatter light. The scattered light rays from particles cutting through the beam are
steered to a photodiode using a system of collection optics. The photodiode converts the image into a
current which is converted to a voltage and amplified by an electronic circuit. The amplitude of the
voltage pulse is proportional to the light scattered, which in turn is proportional to the size of the
particle. The voltage pulses created by the particle are then processed by additional electronics that
analyze the height of each pulse and therefore, the size of each corresponding particle. The result is
that the number of particles of various sizes is determined. The ApexZ is effective in both ultra-clean
areas (such as ISO Class 1 or Grade A) and in more traditional clean zones rated as ISO Class 3 or higher.
Refer to Specifications in this manual for additional instrument information.
