1. A calibration apparatus configured to generate a testing gaseous substance, the calibration apparatus comprising:
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 the 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, wherein the controller component is configured to:
in response to determining that the testing solution is fully transformed, cause the at least the portion of the testing gaseous substance to enter a gas detecting apparatus in conjunction with output of a pump.
