Product name: GY series pointer fruit hardness tester
Firmness score in the series GY-1, GY-2, GY-3 three models for measuring apples, pears, strawberries, grapes and other fruits of the hardness. It is suitable for fruit tree research sector, fruit, fruit farms, tertiary institutions and other units, to cultivate varieties, harvest stored, exported hardness tests involving transport and processing, in order to determine the ripeness of the fruit. The apparatus of small volume, light weight, reading intuitive, easy to carry, especially suitable for field testing. Can also be fitted to support a dedicated test machine use, can improve the accuracy of the test.
Fruit hardness tester design principles
Hardness is the fruit of fruit per unit area (s) of dynamometric spring under pressure (n), which is defined as the ratio of fruit firmness (p).
P =N/S
P-the fruit measured hardness value 105 PA or (kg/m)
N-force spring in Newton or fruit on the n (kg)
S-square of fruit or (cm)

Fruit hardness tester uses methods
Before the measurement: turning the dial, the driven pointer aligns with the dials the first tick (GY-1 for the tick 2, GY-2 and GY-3 for the tick 0.5); Fruit to be measured and cut to about 1 square centimeter of skin.
Measurements: hold the hardness, hardness perpendicular to the test surface of the fruit, head uniform pressure inside the fruit, driving instruction driving pointer pointer rotation when the pressure head pressure to tick (10 mm) stop, direction indicator readings for hardness of fruits, three times the average.
Measurements: turn the zero knob so that the pointer is reset to the initial tick.

Fruit hardness tester notes
1, the measurement should be loosened before tightening the knob, turn the dial will drive the hands (straight) aligned with the initial tick, then spinning solid knob tightly. Check whether the instruction pointer on the right side of the driven pointer, if not, you should turn the zero knob, so that indicates that the pointer on the right side of the driven pointer.
2, in order to achieve better accuracy, measure, using hand pressure head, full scale pressure two or three times, making lubrication.
3, when measuring the hardness, should be even slower insert, not turning pressure into, not to impact measurement.
4, punch with fruit surface must be vertical.
5, GY-1 and GY-2 fruit hardness tester outer unit X10 5 PA, inner ring unit for kg/cm2, GY-3, connection of pressure head, scale readings with inner ring, connecting the low pressure head, outer scale readings.
6, the instrument and the head's clean, measurement is complete clean up the juices.
7, professional at the top of the rack connector is for the professional sector, the parts used to connect with the rack, when a connection is needed, unscrew the knob, screw and rack-mounted and secured screws in holes to screw in.
8, used for more than one year, should open the rear cover, to the spindle, toothed, gem eyes, guiding groove, injecting a small amount of table oil lubrication to improve accuracy and longevity.
9, dynamometric Spring factory-calibrated, no unauthorized turn the nut.
