This semi-permeable membrane tube with braided shield replaces drying colums in gas analyzers and metabolic carts. It instantly reduces moisture to ambient humidity.

Approx 18 inches (45 cm) long x 0.04 inches (1 mm) inner diameter x 1/16" (1.5 - 2 mm) outer diameter tapered hosebarbs.

To install, just cut the sampling line of your gas analyzer and insert Nafion tube. Works bi-directionally, meaning it also humidifies any dry calibration gas.

Note: Alter STPD correction to reflect the presence of ambient humidity, not dry gases.
