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.
ApexZ3 ApexZ50
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.
