Sampling Ports
Sampling ports permit air to flow into and out of the PortaCount Pro
fit tester.
1 The Sample Port is used when sampling air from a respirator
during a fit test. The clear tube marked "SAMPLE" of the Twin
Tube Assembly (
3 ) connects here. The Sample Port fitting is
silver and marked with the letter "S".
2 The Ambient Port is used to sample ambient air during a fit test.
The blue tube marked "AMBIENT" of the Twin Tube Assembly (
3 )
connects here. The Ambient Port fitting is blue and marked with
the letter "A".
3 The Twin Tube Assembly consists of a pair of tubes: the Sample
Tube and the Ambient Tube. The Twin Tube Assembly is about
5.5 feet (1.7 meters) long. The Sample Tube is 7 inches (18 cm)
longer than the Ambient Tube.
The Twin Tube must not be lengthened except for the few inches
added by a Tube Adapter. Never split the ambient and sample
tube, they must remain together and the two sample tubes must
be nearly the same length for accurate fit testing.
