The new APEX range of Casella CEL sampling pumps has been developed to provide sampling capabilities
between 5 millilitres and 5 litres per minute, suitable for a wide range of applications including solvent fumes,
asbestos clearance and personal sampling of dusts.
Two models are available.
APEX (standard),
APEX Pro programmable model.
Both models feature a programmable run
time mode. Merely set the desired
sampling duration, start the pump and let
it run.
The Apex Pro offers advanced and
unique features that are fully realised only
when used with Pump Manager software.
DATA STORAGE: The Apex Pro is
capable of storing up to 100 sets of data,
which include pump start and stop times,
flow rates, average sample temperature,
volume sampled plus any errors that may
have occurred.
COMMUNICATION: This is undertaken
using Pump Manager software and an IR
wireless data link connected to the PC
RS232 port.
operate in four programmable sampling
modes. These are set via the Pump
Manager software. This package allows
the programs to be configured, uploaded
to the pump and data downloaded to the
PC. The following programmable
sampling modes are available.
Duration: A samping duration can be set
via the instrument keypad, as for the
standard model. A duration can also be
set via Pump Manager software.
TWA (Time Weighted Average): The
software calculates a series of on and off
periods to switch the pump on and off
throughout the sampling duration to
achieve the desired exposure time.
User Scheduled Programs: Two
real-time scheduling programmes are
availabl, which allow the operator to
pre-program the pump with start & stop
times. Up to nine on/off routines can be
defined for each user program.
This software is designed and structured
to simplify the day to day management of
all sample data and results. It is used to
configure, and download the APEX Pro
advanced programmable model.
Models in the Apex series are available
as individual pumps or as a component in
a measurement kit, with the appropriate
accessories to suit a particular
application. These include flow
calibrators, sample heads, filter mediums,
tubes, gas bags, laboratory analysis and
training courses.
