Instrument checks trace amounts accurately. Moisture in hermeticallysealed electronic equipment measured by instrument designed for field use. Instrument also measures pressure, volume, and contaminants of gas in sealed enclosure. Plumbing for instrument uses vacuum-tight valves so any portion of instrument cleansed by opening certain valves to vacuum source. To ensure accuracy, manifolds are of minimal volume, each comprising only volume within cross-shaped tubing fittings.
