Based on the measurement result by the measuring means that is a combination of the non-invasive measurement means, encourage the measurement by the next measurement means, to provide a non-invasive cell culture devices and systems to implement a quality inspection. That is, the impedance over time monitored during the culture, and compares the determination of the impedance of the measurement result and a predetermined first threshold value, in the case of less than the threshold and not less than the first threshold, of the change to change the next inspection content depending on the presence or absence.
