Brief Description
The fruit sclerometer (also called fruit hardness tester)
GY-2 model used to testing strawberry, watermelon’s
fruit’s hardness. It is suitable for the fruit tree scientific research department, the fruits company,
the fruit tree farm, unit and so on technical college agriculture colleges and universities, to cultivate
the improved variety, the harvest storage, the product transportation and the processing and so on
by the fruits hardness. Thus judge fruit’s mature degree. This instrument volume small, the weight is light, straight
reads the type, carries conveniently, specially is suitable for the scene determination, the result came out direct.
Measurement Principle
The technician should do two measurements at the opposite sides of each fruit, e.g.,
at the sun-side
and the shadow-side. The point of measurement should be plain and without any fault on the peel.
With this instrument, the user can see the yielding of the fruit under a certain and constant press power
as well as
a defined measuring distance. The indicated measured value is a quotient.
For this reason it is absolutely important that the user always note the anvil employed for the firmness test.
The anvil does not penetrate the peel of the fruit.
Features
Hand-held, analog meter
Light-weight, portable, includes protective carrying case
On-site measurement of fruit firmness indicates maturity or ripeness
Easy to read scale - trailing pointer indicates highest resistance point
Plunger tip marked for accurate penetration depth
Determine fruit quality during harvest, shipping, receiving, processing, storage
Instructions
Before measuring: Rotating dial, justify the dial and driven guidelines and the initial alignment of the
same scale (AGY-1 for the scale of the line 2, AGY-2 and AGY-3 for the scale of the line 0.5); will raze the be measured fruit about 1 cm2 the skin.
Measuring: Hold the sclerometer, make the sclerometer perpendicular to the surface, the pressure head
insert into the fruit indicators, when the pressure head to the scale of pressure (10 mm),it stops, instructions
Objectives of reading instruction is the fruit of hardness, for three average.
Measured:
Rotary knob back to zero, so that indicators reset to the initial scale line.
Pay Attentions
1. Retention knob should be loosened before measuring, rotate dial will justify the driven guidelines
and the initial alignment of the same scale (straight head), and then rotate retention knob.
Check whether the driver instructions pointer is on the right of driver guidelines, if not, should rotate back
to zero knob, so that instruction pointer is on the right of driver guidelines.
2. In order to achieve better accuracy, before measuring pressure the pressure head with their hands
with full range press 2 to 3 times, so that lubrication.
3. When measuring hardness, should be uniformly slow insertion, can not turn pressure, should not impact measurement.
4. Pressure head fruits should be vertical surface.
5. GY-1 and GY-2 type fruit sclerometer scale units for the outer ring is × 105 Pa, the inner ring
scale is kg/cm2, GY-3 type, connecting the small pressure head, with inner ting scale readings,
connecting big pressure head, with the outer ting scale readings.
6. The instruments and pressure head should be kept clean and after finishing measurement it should be
cleaned be cleaned up the juice.
