Abstract: Methods, apparatuses and systems for calibrating gas detectors are disclosed. An example calibration apparatus may have a gas supply element configured to provide a background gaseous substance within at least a portion of the calibration apparatus, a nebulizing element configured to generate the testing gaseous substance by transforming a testing solution in conjunction with the background gaseous substance, a pressure control element configured to regulate airflow in order to maintain a constant air pressure within the at least a portion of the calibration apparatus, and a controller component in electronic communication with the gas supply element, the nebulizing element and the pressure control element.

Abstract: Methods, apparatuses and systems for providing an apparatus such as, for example, a gas detecting apparatus are disclosed herein. An example apparatus may comprise: a manifold defining a gas flow channel that is configured to convey a gaseous substance from a gas inlet on a surface of the manifold; and at least one integrated flow regulating component comprising a filtering element that is configured to filter the gaseous substance, wherein the filtering element is disposed adjacent an orifice that leads to an interior channel of the integrated flow regulating component, and wherein the filtering element is disposed upstream with respect to the orifice.
