HAPSITE Smart Operating Manual
2.10 Probe Sampling Options and Attachments
To expand the sampling range of the HAPSITE sample collecting bags can be used
and special VX Conversion Tubes can be attached.
2.10.1 Probe Nut Assembly
The Probe Nut Ferrule orientation is critical for attaching a bag sample or VX
Conversion Tube. Using a guide (golf tee, small screwdriver, plastic pen cap with
pocket clip extension), place the metal probe nut over the narrow end of the guide
with the threads facing up. Place the small, back ferrule over the narrow end of the
guide with the beveled side facing up. The cone-shaped ferrule should be placed
over the extension with the narrow end facing up. Refer to
Figure 2-51 . Carefully
remove the nut assembly from the narrow end of the guide and gently tap the nut
so that the ferrules seat properly into the nut. Thread the nut-ferrule assembly onto
the probe. Finger-tightening is sufficient.
WARNING
Ferrule orientation is critical to avoid leaks. If sampling a
bag of toxic material, a leak could be harmful to people.

NOTE: Use a guide (such as a pen cap or sharpened

back ferrule orientation.
