GY-3 Digital Fruit Hardness Tester - Portable Fruit Firmness Penetrometer for Measuring Maturity & Ripeness Level - Perfect for Apple, Pear, Peach Testing in Orchards & Farms

Fruit hardness tester is used to judge the maturity of fruits by measuring the hardness of apples, pears, watermelons, bananas and other fruits so as to cultivate good varieties, picking time, processing time, harvest storage, export transportation and other reasonable control of time. It is suitable for use by fruit scientific research departments, fruit farms, fruit companies, universities and other units. The fruit hardness tester is small in size, light in weight, intuitive in numerical display and easy to carry. It is suitable for fruit inspection in various fruit places, and it can also be assembled on a special test stand to improve the accuracy of testing and is suitable for use by professional inspection departments. Fruit Hardness Tester GY-3 Hardness of some common fruits: Apple：8.0~9.2 kg/cm² Plum: 3.4~4.2 kg/cm² Peach: 10.0~13.5kg/cm² Pear:7.5~7.7kg/cm² Kiwifruit: 8.2kg/cm² Grape: 0.2~1.3kg/cm² Strawberry: 0.55~0.68kg/cm² Application of Fruit Hardness Tester GY-1 mainly tests hard fruit, such as apple and pear.GY-2 mainly tests soft fruit, such as strawberry.GY-3 can measure both soft and hard fruit(When connecting small pressure head, use inner ring to scale reading; when connecting large pressure head, use outer ring to scale reading) Fruit firmness (P) refers to the ratio of fruit unit area (S) to the pressure (N) of the pressure spring under tset P=N/S P--Fruit Hardness (10^5 Pa or kg/cm²) N--Force exerted by a force-measuring spring on the fruit surface(N or kg) S--Fruit area of thrust surface (cm²) Instructions of Fruit Hardness Tester Before measuring: Turn the dial to align the drive pointer with the first calibration line of the dial(GY-1 is calibration line 2, GY-2 and GY-3 is calibration line 0.5); Peel the fruit about 1cm2.Measuring: Hold the hardness tester in hand, make the hardness tester perpendicular to the surface of the fruit under test, press the test head into the fruit evenly, then drive the pointer to start driving the indicator to rotate, when the test head stops at the scale line(10mm), the reading indicated by the indicator is the hardness of the fruit, and the average value is taken three times.Measured: Rotate the knob to reset the pointer to the initial calibration line. Pointer Dial Double needle design, peak memory Pointer Dual Units Display Alloy Probe The probe can be disassembled, the test head calibration line can be measured more accurately Fastening Button Turn right to lock dial GY-1 GY-2 GY-3 GYJ Fruit Sclerometer Stand Add to Cart Buying Options Add to Cart Add to Cart Customer Reviews — — 3.9 out of 5 stars 2 — Price $59.00$59.00 — no data $65.00$65.00 $349.00$349.00 Indication Scale 2-15kg/cm2 (×105Pa) 0.5-4kg/cm2 (×105Pa) 0.5-12kg/cm2 (×105Pa) 1-24kg/cm2 (×105Pa) no data Pressure Head Size Φ3.5mm Φ3.5mm Φ11mm & Φ 8mm no data Precision ±0.1 ±0.02 ±0.1 no data Insertion Depth 10mm 10mm 10mm no data Size 140×60×30mm 140×60×30mm 140×60×30mm no data Weight 0.3kg 0.3kg 0.3kg no data
