Principle of fruit pressure meter:
Fruit firmness is the pressure force spring bear some kind of fruit per unit area, and their ratio is defined as the fruit firmness.
(1)P is the measured fruit hardness value of 100000 Pa or kg/cm ²;
(2)N is the spring pressure of the force measuring Newton or kilograms of force at the fruit surface;
(3)S refers to the fruit by force area square meters or square centimeter.
Measurement by fruit pressure meter:
Before measurement: turn the dial, drive pointer and dial scale alignment (GY-1-scale line 2, GY-2 and GY-3 type scale line 0.5); then tested fruit cut go about 1 square centimeters of skin.
Measurement: durometer hardness meter with the hand perpendicular to the surface of the tested fruits, the ram uniformly pressed into the fruit within, drives the pointer at this time to start the drive instruction pointer rotation, when the indenter to the mark at the stop, the hardness of the fruit in the directions indicated by the pointer reading is taken three times average.
After measurement: rotate back to zero knob, the pointer is reset to the initial scale.
|Types of fruit||For example|
|Small fruit||Strawberries, cherry, grape, blackberry, etc|
|Soft fruit||Peach, banana, apricot, plum, melon, citrus, persimmon|
|Strong fruit||Pear, nectarine, kiwi fruit|
GY-1 fruit firmness tester Measures 2-15kg/cm2. Large range ideal for Apples, Peaches, Pears, Avocado, Kiwi, Tomatoes and much more. Fruit firmness one of the most accurate ways to test for a fruits maturity and quality.
GY-2 stainless steel fruit firmness tester has a measurement range of 0.5-4kg/cm 2. The low measurement range makes it ideal for low range fruits such as Citrus, Melons, Plums, Strawberries and other Soft Fruits.
GY-3 stainless steel fruit firmness tester has a dual range that allows you to measures general fruit firmness with a range of 0.5-12kg/cm2. The thinner 8mm tip is ideal for Apples, Peaches, Pears, Avocado, Kiwis and Tomatoes. You can also change the measurement range by swapping tips to the thicker 11mm diameter tip and using the penetrometers dual display to a measurement range of to 1-24kg/cm2 for tougher fruits. This this unique dual dial display it is easy to measure the firmness of nearly all fruits.
1, before the measurement should loosen the tightening knob, turn the dial to the drive the pointer with initial scale alignment, then tighten the fastening knob. Check indicates whether the pointer in the right side of the driver pointer, if not, should rotate back to zero knob so indicating pointer on the right side of the driver pointer.
2, in order to achieve better accuracy, pressure to the pressure head with hand before the measurement, the full scale extreme pressure of two to three times, so that lubrication.
3, hardness measurement, should be uniform and slowly inserted not turn the pressure into the more impact measurement.
4, the indenter and the surface of the fruit should be perpendicular.
5, the GY-1 and GY-2 fruit hardness tester outer scale units × 105 Pa, and the inner ring scale units kg/cm2, GY-3 type, connected to a small pressure head, inner ring scale readings, a large pressure head is connected with the outer scale readings.
1, Stainless steel construction.
2, Comes in a rugged stainless steel carrying case.
3, Features a trailing pointer which will indicate the highest resistance point when testing.
4, Mountable on a test stand for lab testing.
This stainless steel fruit firmness tester has a measurement range of 2-15kg/cm 2. The wide measurement range makes it a great general purpose penetrometer for measuring fruits such as Apples, Peaches, Pears, Avocado, Kiwi, Tomatoes and much more.
Fruit firmness is considered one of the most accurate ways to test for a fruit maturity and quality. By measuring a fruits firmness you can make decisions about when to harvest, which fruits seeds to breed, can make decisions on which fruits to export or transport and for example which fruits should be processed and which fruits should be sold fresh.
Fruit Penetrometers are widely used by universities for fruit research and by fruit companies to make important business decisions.
Please check with your local university extension office to find out what firmness levels are optimum for your growing climate.
