PASSIVE OR PUMPED?
There are two modes in which the SPLIT2 can be used: PASSIVE or PUMPED.
PLEASE NOTE: Go to the section on Sampling (p14) before attempting to use the SPLIT2 in the Pumped mode.
To use in the pumped mode the sensing head must be
configured with the appropriate inlet e.g Inhalable,
Thoracic or Respirable and with a pre weighed filter in
place. The sensor must be mounted on the back plate
pointing forward. See the pictures below and on page
13.
To use in the passive mode the sensing head must be
configured without any inlets or filter cassettes. The
sensor
must be mounted ‘across’ the back plate in
order to allow air movement through it. See the
picture opposite. To fix sensor to the bracket use the
IOM front plate without the O ring in or the threaded
portion present.
For use in the pumped mode an external sample pump
MUST be attached as shown. We recommend the SKC
Sidekick (part # 224-50 or 224-52TX) as your
PREFERRED SAMPLE PUMP. The pump must be set
at a flow rate of 2.0 litres/minute
Passive mode: use sensing head like this
PLEASE NOTE: To configure the sensing head for different dust fraction the IOM inlet with suitable
foam is used as shown below. A preweighed filter must also be fitted.
Active Mode: use sensing head like this
INHALABLE
Filter only
RESPIRABLE
Filter plus WHITE foam
THORACIC

Note; for weighing procedures when using the IOM with foam inserts please refer to the IOM instruction sheet
This O ring is permanently affixed.
