Abstract

A device is presented for use in controlling the quality of a perishable object, while progressing on its supply line, by monitoring the condition of a time-temperature indicator (TTI) associated with the object. The device comprises a sensing assembly for detecting a response of the TTI to a predetermined stimulus and generating measured data representative thereof, said measured data being indicative of the condition of the TTI, thereby enabling the determination of the remaining shelf life of the TTI and thereby any perishable good to which it is attached and calibrated.
