new design sf6 collection dew point

A unique sample cell allows dew point measurement at both in gas pressure and in ambient atmospheric pressure. The cell meets and even exceeds environmental regulations by ensuring protection against accidental discharge of SF6, requiring minimal amount of SF6 for sampling, and enabling collection and recycling of SF6.
