CHAPTER 2
Prepare the PortaCount Fit Tester
for Operation
Install the Twin Tube Assembly
The PortaCount Fit Tester has two inlet fittings, one colored blue and
one colored silver. Connect the twin tube assembly to the
corresponding inlet fittings; the blue tube to the blue fitting and the
clear tube to the silver fitting. The clear tube samples particles inside
the respirator. Ambient particles outside the respirator are sampled
through the blue tube.
C A U T I O N
The twin tube MUST NOT be lengthened except for
the few inches added by a tube adapter. NEVER split
the ambient and respirator tubes, they must remain
together and the two sample tubes must be nearly the
same length for accurate fit testing.
