1. A turbidity calibration-correction apparatus configured for an automated calibration-correction of a turbidity, the turbidity calibration-correction apparatus comprising:
a turbidity calibration standard configured for calibration of a turbidity measurement apparatus;
a communicator configured to transfer at least an identity of the turbidity measurement apparatus and a correction-value from the turbidity measurement apparatus to the turbidity calibration-correction apparatus; and
a memory configured to store an attribute-value comprising at least the correction-value that is a function of a turbidity value of the turbidity calibration standard measured by the turbidity measurement apparatus, wherein the automated calibration-correction is based on the correction-value,
wherein the attribute-value is a value-pair representing a relation between the turbidity calibration standard as a first relation-value and the turbidity measurement apparatus as a second relation-value, and wherein the attribute-value further comprises at least one of: a last-calibration value, a minimum-calibration value, a maximum-calibration value, a last-calibration date, and a correction-data of the turbidity measurement apparatus.
