The use of fruit hardness tester and precautions

The application of fruit hardness tester can reasonably grasp the maturity of apples, pears, watermelons, bananas and other fruits, as well as the cultivation of improved seeds, picking time, and processing time. This is mainly determined by measuring the hardness of fruits with a fruit hardness tester. from. It is suitable for fruit tree research departments, fruit tree farms, fruit companies, universities and other units.

The fruit hardness tester is small in size, light in weight, intuitive in reading, and easy to carry. It is especially suitable for on-site testing. Can also be mounted on a dedicated test bench to improve the accuracy of the test. Instructions:

Before measurement: Turn the dial so that the drive pointer is aligned with the first tick mark on the dial (the GY-1 is the tick 2, the GY-2 and the GY-3 are the tick 0.5); cut the fruit to be tested About 1 square centimeter of skin.

Measure: Hold the fruit hardness tester by hand and make the fruit hardness tester perpendicular to the surface of the fruit to be measured. The indenter is evenly pressed into the fruit. At this time, the driving pointer starts to drive and instruct the pointer to rotate. When the indenter is pressed to the mark (10 mm) Stop and instruct the reading indicated by the pointer to be the hardness of the fruit, taking the average of three times.

After measurement: Rotate the zero return knob to reset the pointer to the initial scale line.

Notes on the use of fruit hardness tester:

Before the measurement, the fruit hardness tester tightening knob should be loosened. Turn the dial to align the drive pointer (straight) with the initial scale mark, and then tighten the tightening knob. Check to see if the pointer is on the right side of the drive pointer. If it is not, rotate the zero return knob so that the pointer is on the right side of the drive pointer. In order to achieve a better accuracy, before the measurement, press the head with a hand, and then press the full-range two or three times to lubricate it. When the hardness is measured, it should be inserted evenly and slowly, and it must not be rotated and pressed in, nor can it be impacted.

PCB Cutting Machine

This type of SF-706 machine have to keep PCB board,the circular blade is moving.It is suitable for Special height for ultra high component can be 70mm.

This type of SF-701machine through adjust the height of track manually and control At 0.01 mm to solve the problem of V-CUT depth. Accept made to order super high components on the PC board such as power supply.The highest for 400mm is also accepted to customize.

The type of SF-705 v notch PCBA Cutting Machine which is suitable for Thickness of the to-be-cut base plate: 0.5-2.0mm, max. length of 300mm PC plate. Then Processing V-PCD plate, aluminum plate and CUT plate, etc.The using way is Controlled by electric pedal or pneumatic pedal, hoe knife plate splitting is completed by the motion of air cylinder.

The type of SF-716 machine is used for visual PCB depanel.
