Disclosed herein is a system (11) for evaluating agricultural material which comprises, in one embodiment, a housing (102) having a passage (104) in or through an interior (106) of the housing (102) with an inlet (108) for receiving agricultural material and an outlet (110) for outputting the agricultural material. The system further comprises a wall opening (112) in a wall (109) of the passage. An imaging device (116) having a lens (118) is located inward from a border (120) of the imaging device. The imaging device (116) is pivotally mounted for rotation with respect to a housing (102) such that in a closed state the border (120) of the imaging device rests on, engages or interlocks the wall opening (112) of the housing (102), and in an open state the border (120) exposes the wall opening (112) and an interior (106) of the housing (102).
