Abstract

An apparatus for determining the quality of meat comprising a probe (1) to be inserted into a piece of meat which is to be examined and reflection measuring means placed in the probe having a light emitter (2) and a light receiver (3). A reference light receiver (4) which controls the supply to the light emitter (2) is placed in the probe near the light emitter. The servo link formed will compensate for the fluctuating efficiency of the light emitter (2) and the light receiver (3). The intensity of the light emitter may automatically be kept at a constant level.
