Evaluation of commercially available submersible pressure gauges

Fourteen commercially available submersible pressure gauges were evaluated by the Navy Experimental Diving Unit to determine accuracy and watertight integrity. The gauges tested represent a realistic survey of the market. While not every gauge currently sold in the U.S.A. was tested, the results of this test are felt to represent the general state-of-the-art in gauge design and manufacturing technique. As a result of unmanned testing, and due to the overall quality of design and construction, it is recommended that submersible pressure gauges be designated as open purchase items on the list of equipment Approved for Navy Use (ANU). It should be emphasized to all divers that submersible pressure gauges should be given the same care as that given other life supporting equipment.
