The new developments in HVI SPECTRUM measurements are introduced and discussed. The emphasis is given on improved color and trash measurement, the new automated sampling technique, and the new maturity index and moisture measurement. The maturity index is explained and compared to the AFIS maturity ratio. The new moisture measurement is compared to a standard hand-held moisture probe. Sample moisture and its variance is discussed and related to the conditioning of samples and the required air conditioning equipment in the laboratory. A mill trial shows the result of the application of the moisture correction algorithm introduced for the first time with the HVI SPECTRUM.
