Fruit Hardness Tester (Fruit Sclerometer)
Model: FR-5120 (20 kilogram)
Make: Lutron (Taiwan)
The hardness of fruit (P) can express by unit area (S) divided by the pressure of dynamometer (N).
P = N / S
P = Hardness value of fruit ( Kg/cm2 )
N = Pressure of dynamometer ( N, Kg, LB )
S = Area of pressure ( m2, cm2 )
Range of 0 to 13 Kg (Appropriate for fruits such as apples, pears, peaches or kiwis) with the 6mm diameter tip (FRTP-6) or 11mm diameter tip (FRTP-11).
Range of 0 to 20 Kg (Appropriate for very hard fruits) using the 11mm diameter tip (FRTP-11).
