The "gasometer" is a device that measures differential dissolved gas pressures (δP) in water relative to barometric pressure (as does the "Weiss saturometer"), but operates continuously without human attention. The gasometer can be plumbed into a water supply system and requires 8 liters/minute of water or more at 60 kilopascals. The gasometer's surfaces are nontoxic, and flow through
