Scale values: 11mm: 0.5-12kg/cm, 8mm: 1-24kg/cm ⑨. Depth of indentation: 10mm ⑩. Both soft and hard fruits can be measured ⑪. 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 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.
