Definition : Detectors designed for automated discovery and/or ascertainment of the presence of some physical, chemical, or other conditions and elements in the environment to which individuals may be exposed. These detectors may be computerized and have capabilities to process information. Environmental detectors are used mainly to determine the presence of abnormal concentrations of gases (e.g., oxygen, carbon dioxide), hazardous substances (e.g., toxic gases, chemical and biological agents), and/or other physical conditions in the environment (e.g., high or low temperatures, ionizing radiation, high particle concentration). Many environmental detectors warn of a hazardous condition when predetermined substance concentrations have been reached or exceeded.
