A breath alcohol device calibration system includes a computerized calibration module operable to calibrate a candidate breath alcohol device using a reference gas of known alcohol concentration, and a reference gas tank identification module operable to identify a reference gas tank that is coupled to the breath alcohol device calibration system. Identification is performed using at least one distinguishing characteristic of the coupled tank, the distinguishing characteristic providing reference gas tank information including at least the known alcohol concentration of gas in the reference gas tank. The reference gas tank identification module is further operable to read a temperature history of the tank from an electronic device coupled to the tank, and to indicate an error condition if the temperature history of the tank indicates temperatures below a first temperature threshold over the tank's recent temperature history to potentially result in incomplete mixing of the reference gas.
