Abstract
A resin purger which reliably determines when purging is completed and prnts humid air from re-entering the purged material. A sealed container has an inlet valve attached to a source of inert purge gas and an outlet valve. A diffuser is connected to the outlet valve to screen the exit gas from the container. A probe sensor detects the amount of oxygen in the exit gas and indicates when purging is complete.
