Phase III: Laboratory Investigation of Portable Instruments for Submarine Air Monitoring
Abstract
Drager tubes are currently used to supplement the atmosphere analysis measurements made aboard U.S. Navy submarines. The submarine fleet has requested that these tubes be replaced with a less labor intensive measurement system. Due to recent developments in gas sensing instrumentation, it is possible to replace many of the existing detectors with instruments that will incorporate more than one sensor at a time. This report is a continuation of an evaluation of portable instruments for use in submarines as air monitors. This is the third phase of a three-phase program concerned with investigating potential detection methods to replace the Drager tubes. Phase III evaluated sensors for nitrogen dioxide, ammonia, sulfur dioxide, chlorine, hydrogen, and ozone. The chlorine and ozone sensors did not have sufficient sensitivity to detect the Navy 90-day limits. All of the manufacturers have ammonia sensors that can detect the 90-day limit. The Drager ammonia was the best overall. The Omni nitrogen dioxide sensor was best overall for that test gas. The hydrogen sensors performed well. The sulfur dioxide sensor is not satisfactory.
