6. Infrared open-path detector - Wikipedia

   en.wikipedia.org/wiki/Infrared_open-path_detector

   An open path detector usually costs more than a single point detector, so there is little incentive for applications that play to a point detector's strengths: where the point detector can be placed at the known location of the highest gas concentration, and a relatively slow response is acceptable. The open path detector excels in outdoor ...
