- Abstract
- The Navy Clothing and Textile Research Unit (NCTRU) has evaluated an oxygen-sensing warning device, developed by Beckman Instruments, Inc., to be used as a safety feature in a Damage Control Suit System (DCSS) presently under development. The O2 warning device, which employs a polarographic oxygen sensor in conjunction with control electronics and a visual output, provides a visual warning in the event oxygen concentrations in the DCSS are above or below certain preselected thresholds. Evaluation of the device showed it to be a reliable and accurate monitor of oxygen concentration. Its responses to changes in other environmental factors, such as temperature and humidity, were small. Donsequently, the O2 sensing warning device was judged suitable for use in the DCSS.
