    Abstract: A container box, having: a container controller for controlling the container box, one or more pressure transducers disposed within the container box, the one or more pressure transduces operatively connected to the container box, wherein the container box is configured for monitoring pressure within the container box with the pressure transducers, the container box configured to perform an airtightness test, including: pressurizing the container box until pressure in the container box is above a first threshold; monitoring pressure in the container box to determine when pressure in the container box is proximate the first threshold; monitoring a first duration during which pressure in the contain box drops from the first threshold to a second threshold; determining whether the first duration is within an acceptable range, and when the duration is outside the acceptable range, communicating an alert to a container box monitoring implement.
