The 3003D uses air sampling tubes to provide a cross sectional sampling of air moving through the duct. Inlet sampling tubes are available in four lengths: one foot, three feet, six feet, and ten feet. The desired length must be specified when ordering. See the "Ordering Information" section for details.

The length of the inlet sampling tube is determined by the width of the duct to be monitored, The inlet duct should cover the entire width of the duct, therefore, specify the shortest sampling tube that is at least the width of the duct to be protected. It can then be cut to the exact length at the job site.
