Tube length is an estimate of how long the tube attached to the pump is. This value is customizable from the Pump options menu and factors into sample time. G7’s multi-gas pump cartridge supports maximum tube lengths of:

• 100 ft of 0.188” diameter tube (30.2 m x 4.78 mm) or,

• 50 ft of 0.125” diameter tube (15.25 m x 3.17 mm).

G7 pump settings can be found in the Device settings menu. For more information, see Configuring Tube (Hose) Length.
