AIR SAMPLING TUBE
First Claim
1. An air sampling tube comprising:
- a tubular section having a sidewall defining a tube interior and a tube exterior, said sidewall having an axially extending groove defined by a first edge and a second edge of said sidewall, the groove providing air communication between the tube interior and the tube exterior, said tubular section having a proximal tube end and a distal tube end, the proximal tube end joined to a housing having an air sampling sensor.

Abstract
An air sampling tube is provided that provides superior air flow, strength, and manufacturability and couples to an air sampling sensor housing. The sidewall of the tubular section has an axially extending groove. To facilitate installation and inspection, an air sampling tube is provided with a starter cap. An end cap prevents air flow through the distal end of the tube. An air sampling tube is provided that assures proper axial positioning of tubular section apertures through resort to a coupler with a rotationally asymmetric joining element. A modular kit is provided that allows for custom installation without resort to cutting or forming operations in the field.

10. An air sampling tube comprising:
-
a tubular section having a sidewall defining a tube interior and a tube exterior and at least one aperture providing air communication between the tube interior and the tube exterior, said tube section having a proximal end and a distal end; a starter cap having a choke, the choke having a shaped aperture that partially occludes air flow within said starter cap and indicating orientation of the at least one aperture, said starter cap joining said tubular section to a housing containing an air sampling sensor; and a coupler or end cap attaching to the distal end of said tubular section. - View Dependent Claims (11, 12)

13. An air sampling tube comprising:
-
a first tubular section having a first sidewall defining a tube interior and a tube exterior and at least one aperture providing air communication between the tube interior and the tube exterior; a second tubular section having a second sidewall defining a tube interior and a tube exterior and at least one aperture providing air communication between the tube interior and the tube exterior; at least one rotationally asymmetric coupler intermediate between said first tubular section and said second tubular section and having a first joinder portion of a blade or first portion receptacle, the first portion blade or the first portion receptacle being friction fit complementary to a first tube end of said first tubular section, said coupler having a second joinder portion joined to a second tube end of said second tubular section to form an air communication conduit therethrough with only a single orientation between said first tubular section and said second tubular section. - View Dependent Claims (14, 15, 16, 17)
