Abstract: An assembly for measuring the condition of fruit and vegetable is disclosed which comprises an expandable resilient bellows arrangement (10) having a passive sensor (22) mounted therein. In use, the bellows (10) can be expanded so as to bring the passive sensor (22) into contact with, or adjacent to, and item of fruit or vegetable whereby the sensor can react to a property of the fruit or vegetable and produces a signal related to that property. The bellows (10) can the be contracted away from the fruit or vegetable. The sensor (22) can detect the properties of, for example, surface gas detection, chlorophyll fluorescence, visible and Near Infra Red spectrometry and change transfer. An arrangement is also disclosed in which a plurality of bellows (10) are mounted on a rotatable mounting (510) whereby by rotation of the mounting (510), the bellows (10) can be brought sequentially into a position in contact with, or adjacent to, a respective fruit or vegetable.
