Abstract
The present disclosure relates to system, method and apparatus including a chemically impregnated media, a fixed, white broad spectrum LED source, a recording device having a digital imaging sensor and a microprocessor, is provided. The recording device captures real-time video images of color changes that occur on the chemically treated media during exposure to a gas specimen indicating a targeted substance is responding on the media. The continuous video images are transmitted to the microprocessor and evaluated with a proprietary algorithm loaded onto the microprocessor, which can efficiently determine gas concentration, as well as, individual species of target gas or gases landing on the specific chemically treated media. The captured video recording of the media color change provides a record of the events for later verification and evaluation of a particular gas detection event.
