Humidity bottles are made from type 316 stainless steel. Swagelok fittings for gas inputs and outputs are welded into the bottle. Nafion tubing is coiled in the bottle to provide dew-point humidity level for the gas passing through the tubing. The bottle is insulated
and heated using a silicone rubber flex-pad.
Test conditions: The humidity bottle controller was set to 80 deg C and allowed to stabilize at “Gas Inlet” conditions. After stabilization the “Outlet
DP deg C of the humidity bottle was measured. Test was administered using 1 m of nafion
tubing.
