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.
