Hardness Tester, GY-1 Fruit Sclerometer Durometer Fruit Pear Hardness Tester Penetrometer,Excellent Portability

Model No.: GY-1 Fruit hardness (also known as fruit hardness or fruit durometer) It is suitable for fruit research departments, fruit farms, fruit companies, universities and other units. The instrument is small, lightweight, with numerical display and intuitive, easy to carry, suitable for all kinds of fruits for fruit inspection sites. It can also be installed on a dedicated machine which is used to improve the accuracy of the test when applied to the professional inspection department. Design principle Fruit hardness per unit area (S) to withstand spring force pressure (N), which is defined as the ratio of fruit firmness (P). P = n/s P-105 Pa measured values of fruit hardness or (in kilograms per square meter) N-force spring force against fruit surface or N Newton (kg) S- fruit force area m2. O (cm) Notes: To achieve greater accuracy, measure before pressing the head with your hand, two or three times the extreme pressure to complete the lubrication. When measuring the hardness, the slow insert should be uniform, can not rotate the thrust for not impact the measurement. pressure should be perpendicular to the surface of the head and fruit. Fruit hardness outer e units type GY-1 and GY-2 × 10 5 Pa, internal e units kg/cm2, type GY-3, connect a small head, with the reading of the internal e when connected to a large head, with the readings of the outer e. The instrument and pressure head are kept clean and the measurement of the clean juice is completed. The upper end is a professional frame connector for professional inspection department, connected to the chassis components needed to connect, unscrew the knob, with screws can be screwed holes for screws inside the frame. If s

• Before measurement: Turn the dial to align the first line of e pointer dial (GY-1 line type of e 2, GY-2 and GY-3 line type of e 0.5); Cut the fruit to test 1 cm2 of skin around.
• Measurement: with the hardness of the hand, total hardness measured perpendicular to the surface of the fruit, the penetrator is pressed into the fruit evenly, then a pointer indicating the start of driving for driving hands rotates, when the pressure on the line (10 mm) of the stop, the pointer reading goes indicating the hardness of the fruit, the average times taken.
• After measurement: Turn the knob back to zero, so that the pointer is reset to the initial mark.
• The measurement should be loosened before tightening the knob, turn the dial to make the pointer line (straight) align with the original e, and then tighten the fixing knob. Check that the instruction pointer is a pointer to the right of the driver, and if you find that it is not, you need to turn the knob again to zero, so that the right side on the driving instruction pointers.
• The product is divided into three models GY-1, GY-2, GY-3 used to measure the hardness of apples, pears, watermelons, bananas and other fruits, to determine fruit maturity, reasonable grip seed cultivation, harvest time, processing time, harvest storage, export and harvest transportation.
