DescrizioneThe HFH81 Ripeness/Hardness Tester is a hand-held compact penetrometer for fruit firmness testing, the universally accepted measure of ripeness. This tester is the growers’ indispensable tool for knowing when to pick and ship. The HFH81 Series fruit tester measures the force required to push a plunger tip of specified size into the fruit pulp. The force reading assists in determining the appropriate picking time or monitoring fruit softening during storage. Because of the number of fruit varieties, geographical locations and other variations, the appropriate firmness for harvesting will vary. The user must combine experience and expertise to establish the firmness value that applies to their specific variety and locale.
