South African Avocado Growers ’ Association Yearbook 1998. 21:19-21 Non-Destructive Avocado Fruit Firmness Measurement

Of the various instruments evaluated in this study, the hand-held densimeter gave the, best results. The densimeter measured avocado fruit firmness 5 times faster than the conventional firmometer. On Fuerte, the densimeter also proved more accurate than the firmometer. On Hass, however, the repeatability of two densimeter readings on one fruit was slightly lower than that of two firmometer readings. The densimeter is recommended for non-destructive avocado fruit firmness measurement
