391-01 “Calidaptor” Calibration
Adaptor
This Calidaptor is designed for use
with the following sampling heads:
• 225-70A I.O.M. inhalable
sampling head in plastic with
plastic filter cassette
• 225-76A I.O.M. inhalable
sampling head in stainless steel
with stainless steel filter cassette
• 225-79A I.O.M. inhalable
sampling head in plastic with
stainless steel filter cassette
• 225-50 Seven hole sampling head
• 225-52 Single hole sampling head
A Calidaptor designed specifically for
use with the cowled asbestos heads
is also available (part no. 391-05).
The SKC Calidaptor allows the flow
setting of a sampling train without the
problems of holding the head, pump
and adjusting the flow all at the same
time.
A hinged bracket and clamping
screw hold the sampling head
securely against a closed pore foam
ring providing a leak proof joint.
The Calidaptor can either be
screwed directly into the outlet of
SKC rotameters (390, 391 and 392
series only) with an ‘O’ ring providing
a leak proof joint, or connected to
other flow measuring devices using
the supplied screw-in hosetail and a
length of flexible tubing.

Use with SKC rotameters
The Calidaptor is screwed into the top
(outlet port) of the rotameter, tightening
enough to just compress the ‘O’ ring
sealing it to the rotameter.
Pass the sampling head through the
hinged bracket, and rest its inlet against
the foam ring. Clamp the sampling head
in place with the plastic clamping screw
until the foam ring is compressed by
approximately 1mm.
Connect the sample head outlet hosetail
to the pump inlet with a length of tubing.
Use with other sampling heads
With the Calidaptor fitted to the top of
an SKC rotameter, screw the supplied
hosetail fitting into the threaded hole
inside the Calidaptor bowl. Connect
from the hosetail to the inlet of the
sampling head with a length of flexible
tubing.
Note: If subsequently calibrating an
I.O.M. (or similar) sampler, especially
if used with a foam insert, ensure that
the hosetail is removed from inside the
Calidaptor bowl.
Use with other types of calibrator
The Calidaptor can be used as
described above, with any other type
of flow calibrator, by screwing the
supplied hosetail into the threaded hole
in the inlet of the Calidaptor. Connect
from the hosetail to the flow calibrator
with a length of flexible tubing.
