Apex Pro I.S. (Intrinsically Safe version of the Apex Pro).
Please consult Casella CEL for information about upgrading a standard model to an Apex Pro or an Apex I.S.
to an Apex Pro I.S. The instrumentation is available as individual pumps or as complete kits with the
appropriate accessories to suit particular applications and is supported by our training and service facility at
Bedford.
The Apex was developed to provide sampling capabilities between 5 ml/min and 5 l/min (4 l/min for I.S.
versions), suitable for a wide range of applications including solvent fumes, asbestos clearance and
personal sampling of dusts. Apex pumps are ideally suited to many of the “Total” and “Respirable” dust
sampling techniques detailed in the U.K. Health and Safety Executive’s publication MDHS14, and in other
reference methods.
The information contained in this handbook relates only to the operation of Casella CEL sampling equipment
and is not intended to advise or influence your adopted sampling strategy. For advice on appropriate
sampling methods, refer to local legislation and guidelines as dictated by the relevant national and regional
health and safety organisations.
