The device and method in order to watch the culture of the independent nutrition living thing

摘要

Method includes the step (508) which identifies the chlorophyll concentration parameter (CCpOD) value (408) per unit optical density making use of the chlorophyll density measurement value (504) of the independent nutrition culture (104) and the optical density measurement value (506) of the aforementioned independent nutrition culture. In addition as for aforementioned method, also the step (510) which identifies the change in the aforementioned independent nutrition culture making use of aforementioned CCpOD value includes. As for the change in the aforementioned independent nutrition culture, whether or not aforementioned CCpOD value is outside the upper part control limit (404) and the bottom control limit (406) deciding, it is possible to be identified by. Above aforementioned and as for the bottom control limit, it is possible, to be identified making use of the CCpOD value to which predetermined number is already decided as for the CCpOD value which aforementioned already is decided, when the aforementioned independent nutrition culture is a known healthy state, it is possible to be calculated. It is possible, for plural CCpOD values to be calculated, predetermined number (for example 1 or it is possible to be able to give out to the case where plural) aforementioned CCpOD values are above aforementioned and outside the bottom control limit, warning (120).
