ABSTRACT:
An air contamination detector for a scuba unit includes a transparent tube having a lumen, the lumen being user visible for a full 360.degree. about its circumference. A contamination indicator is positioned within the lumen and is exposed to air flow from the air supply of the scuba unit. The contamination indicator is responsive to a contaminant to manifest a change that is visible through the transparent tube. A quick connect/disconnect air connection is affixed to one end of the transparent tube and mates with a low pressure fitting that communicates with the scuba air tanks. A further quick connect/disconnect air filling is positioned at another end of the transparent tube and is connectable to a hose that provides air inlet control for a buoyancy control vest. Since the air inlet control includes a user-operable air inlet valve, air quality within the air tanks can be tested simply by depressing the buoyancy control air inlet valve to enable air to pass through the transparent tube and over the contamination detector.
