Product Description

Fruit hardness FD-1 FD-2, FD-3, use to testing apple, pear, strawberry, grape's fruit's hardness. It is suitable for the fruit tree scientific research department, the fruits company, the fruit tree farm, unit and so on technical college agriculture colleges and universities, to cultivate the improved variety the harvest storage, the product transportation and the processing and so on by the fruits' hardness. Thus judge fruits' mature degree.

Principle of fruit pressure meter:
Fruit firmness is the pressure force spring bear some kind of fruit per unit area, and their ratio is defined as the fruit firmness.
 P=N/S, 
(1)P is the measured fruit hardness value of 100000 Pa or kg/cm ²; 
(2)N is the spring pressure of the force measuring Newton or kilograms of force at the fruit surface; 
(3)S refers to the fruit by force area square meters or square centimeter.
 
 
Measurement by fruit pressure meter
Before measurement: turn the dial, drive pointer and dial scale alignment (GY-1-scale line 2, GY-2 and GY-3 type scale line 0.5); then tested fruit cut go about 1 square centimeters of skin.
Measurement: durometer hardness meter with the hand perpendicular to thesurface of the tested fruits, the ram uniformly pressed into the fruit within, drives the pointer at this time to start the drive instruction pointer rotation, when the indenter to the mark at the stop, the hardness of the fruit in the directions indicated by the pointer reading is taken three times average.
After measurement: rotate back to zero knob, the pointer is reset to the initial scale.
 
Fruit pressure meter Precautions:
1, before the measurement should loosen the tightening knob, turn the dial to the drive the pointer with initial scale alignment, then tighten the fastening knob. Check indicates whether the pointer in the right side of the driver pointer, if not, should rotate back to zero knob so indicating pointer on the right side of the driver pointer.
2, in order to achieve better accuracy, pressure to the pressure head with hand before the measurement, the full scale extreme pressure of two to three times, so that lubrication.
3, hardness measurement, should be uniform and slowly inserted not turn the pressure into the more impact measurement.
4, the indenter and the surface of the fruit should be perpendicular.
5, the GY-1 and GY-2 fruit hardness tester outer scale units × 105 Pa, and the inner ring scale units kg/cm2, GY-3 type, connected to a small pressure head, inner ring scale readings, a large pressure head is connected with the outer scale readings.
 
Fruit classification:
Types of fruitFor example
Small fruitStrawberries, cherry, grape, blackberry, etc
Soft fruitPeach, banana, apricot, plum, melon, citrus, persimmon
Strong fruitPear, nectarine, kiwi fruit
Hard fruitAvocado
