Fruit hardness refers to the pressure (N) that a unit area (S) of fruit can withstand from a force measuring spring, and their ratio is defined as fruit hardness (P). 12. P - The hardness value of the tested fruit is 105 Pa or (kilograms per square meter) 13. N - The force exerted by the force spring on the fruit, measured in or kilograms 14. S - The area of force on the fruit in square centimeters 15. Attention: When connecting a small pressure, read with the circle scale. When connecting a large pressure, read with the outer circle scale. 16. Colour: As Shown 17. Material: aluminum stainless steel 18. Package Contents: 1 * Fruit hardness tester 19.
