GY-1 Fruit Sclerometer Durometer Fruit Apple Pear Hardness Tester Penetrometer

Description

Fruit hardness also known as fruit or fruit durometer hardness

Model: GY-1

The product is divided into GY-1, GY-2, GY-3 three models used to measure apples, pears, watermelons , bananas and other fruits of hardness , to determine the maturity of the fruit , the cultivation of a reasonable grasp seeds, harvesting time , processing time , harvest storage, export and transportation of picking. It is suitable for fruit research department , fruit farms, fruit companies, universities and other units. The instrument is small, light weight , numerical display and intuitive, easy to carry, suitable for all kinds of fruit for fruit inspection sites . Can also be fitted on a dedicated machine used to improve the accuracy of the test when applied to the professional inspection department .

Design principle

Hardness of fruit per unit area S to withstand the pressure of the spring force N, which is defined as the ratio of fruit firmness P.
P = N / S
P- 105 Pa measured hardness values of fruit or in kilograms per square meter
N- force spring force against the surface of the fruit or N Newton kg
S- fruit force area sq.m. or cm

Usage

Before measurement : Turn the dial to make the drive the first pointer dial scale line aligned GY-1 type of scale line 2,GY-2and GY-3 type of scale line 0.5 ; slashing fruit to be tested 1 cm2 of skin around .
Measurement : with the hand hardness, total hardness measured perpendicular to the surface of the fruit , the indenter is pressed into the fruit evenly , then a pointer indicating the start of driving for driving the hands rotate , when the ram pressure to the line 10 mm of the stop , reading the pointer is indicating the hardness of the fruit , the average times taken .
After the measurement : Rotating the knob back to zero , so that the pointer is reset to the initial mark.

Notes

The measurement should be loosened before tightening the knob , turn the dial to drive the pointer straight line is aligned with the original scale , and then tighten the fastening knob. Check the instruction pointer is a pointer to the right of the driver , and if you find it is not, you should rotate the knob back to zero , so that the right side in the driving instruction pointer pointers.

In order to achieve better accuracy, measured before hand pressure head , two to three times the full-scale extreme pressure to make lubrication.

when measuring the hardness , slowly insert should be uniform , can not turn the push , not to impact measurement.

the pressure should be perpendicular to the surface of the head and fruit .

GY-1and GY-2 -type fruit hardness outer scale units × 10 5 Pa, the inner scale units kg/cm2, GY-3 type , connect a small head , with the inner scale reading when connected to a large head , with the outer scale readings.

the instrument and the pressure head kept clean , clean juice measurement is completed .

the upper end is a professional rack connectors for professional inspection department , connected to the chassis components needed to connect , unscrew the knob , with screws Screw holes inside the rack can be screwed on.

the use of more than one year , you should open the back cover to the spindle , gear , gems eye , such as injection of a small amount of table guide groove oil lubrication to improve the accuracy and extend the life of the instrument.

the force of the spring factory calibration, no unauthorized turn the nut.
