Fruit Penetrometer Hardness Tester

FP-501 mainly tests soft fruits, such as apple, pear, strawberries & grapes etc.
FP-502 mainly tests hard fruits, such as cantaloupe.
Soft and hard fruit both can be measured with FP-503

Terminology:
Fruit firmness (P) refers to the ratio of fruit unit area (S) to the pressure (N) of the pressure spring under test.
P=N/S
P一Fruit hardness (10^5 Pa or kg/cm²)
N一Force exerted by a force-measuring spring on the fruit surface(N or kg)
S一 Fruit area of thrust surface (cm²)
