The Naval Surface Warfare Center, Panama City Division is seeking information on commercially available handheld gas analyzers for confined space entry and post-fire atmospheric monitoring in shipboard fire response. Required devices must be highly portable, weighing under 5 pounds, and deployable in under 3 minutes. They must simultaneously detect and monitor O2, LEL, CO, H2S, and VOC. The ideal solution should support an extended calibration-free interval of at least 12 months and include a simplified, rapid field-sensor replacement process to minimize shipboard maintenance. The requesting command is located at Panama City, Florida.
