ABSTRACT:
A portable detector of combustible or explosive gases incorporates a polymeric-type sensor or sensor array coupled to a programmed processor which carries out an evaluation of one or more signals from the sensor or array to evaluate the presence of combustible or explosive vapors. Non-polymeric sensors such as temperature sensors, humidity sensors and/or pressure sensors can also be incorporated and their outputs evaluated to compensate the outputs of the sensor or array of sensors. The detector can be housed in a sealed enclosure and energized by a battery.
