About Fruit Penetrometer
Fruit Hardness Tester
- Fruit hardness tester or Fruit Penetrometer: used to measure the hardness of apples, pears, watermelons, bananas and other fruits, to determine the maturity of fruits, to cultivate good varieties, picking time, processing time, harvest storage, export transportation and other reasonable control of time.
- It is suitable for fruit research departments, fruit farms, fruit companies, universities and other units. The instrument is small in size, light in weight, intuitive in numerical display and easy to carry. It is suitable for fruit inspection in various fruit venues.
- It can also be assembled on a special test stand, which can improve the accuracy of testing and is suitable for professional testing departments.
- Fruit Penetrometer Hardness Tester Soft and hard fruit both can be measured with FP-503
Terminology:
- Fruit firmness (P) refers to the ratio of fruit unit area (S) to the pressure(N) of the pressure spring under test.
- P=N/S
- P Fruit hardness (10 5 Pa or kg/cm2)
- N Force exerted by a force-measuring spring on the fruit surface(N or kg)
- S Fruit area of thrust surface (cm2)
Using Steps:
- Before measurement: Turn the dial to align the drive pointer with the first calibration line of the dial ( calibration line 0.5) Peel the fruit about 1 cm2 .
- Measurement: Hold the hardness tester in hand, make the hardness tester perpendicular to the surface of the fruit under test, press the test head into the fruit evenly, then drive the pointer to start driving the indicator to rotate,
- When the test head stops at the scale line (10mm) the reading indicated by the indicator is the hardness of the fruit, and the average value is taken three times.
- After measurement: Rotate the knob to reset the pointer to the initial calibration line.
Precision Measurement for Fruit QualityThe Fruit Penetrometer delivers reliable and precise assessment of fruit firmness, essential for determining optimal ripeness. Its measuring range spans 1-20 kg/cm with a fine accuracy of 0.1 kg/cm, ensuring consistent results for growers, distributors, and retailers. The analog dial provides instant feedback during testing, while interchangeable tips allow adaptation for various fruit specimens.
Robust and User-Friendly DesignBuilt with a stainless steel body for longevity, the penetrometer features a comfortable non-slip handle. Its hand-held, manual operation allows tests anywhere, without the need for external power. The device is lightweight (1.4 kg) and comes packaged individually for convenience.
Comprehensive Accessories and Easy CalibrationEach unit is supplied with a protective carrying case, spare pressure tips, a user manual, and detailed calibration instructions. This ensures users can maintain accuracy and efficiency during multiple testing operations.
FAQs of Fruit Penetrometer:
Q: How does the Fruit Penetrometer determine fruit firmness or ripeness?
A: The Fruit Penetrometer measures the pressure required to penetrate the flesh of a fruit using interchangeable 8 mm or 11 mm tips. The analog dial displays the firmness value instantly, helping users assess ripeness and suitability for harvesting or sale.
Q: What fruits can be tested with this penetrometer?
A: This device is suitable for small and medium fruits such as apples, pears, peaches, kiwis, avocados, and tomatoes. Its design and interchangeable pressure tips accommodate a variety of similar fruits.
Q: When should I use the Fruit Penetrometer for optimal results?
A: For accurate ripeness assessment, use the penetrometer during harvest periods, routine quality control, or prior to shipping. Immediate readings allow timely decisions in orchards, markets, and warehouses.
Q: Where is the Fruit Penetrometer best utilized?
A: The portable and manual nature of the device makes it ideal for use in fields, packing houses, research labs, wholesale markets, and retail environments throughout India.
Q: What is the process for testing a fruits hardness with this equipment?
A: Choose the correct pressure tip, position it on the fruits surface, and press manually according to instructions provided in the user manual. The analog dial registers the firmness value, which can then be recorded or compared against quality standards.
Q: How does the calibration procedure work?
A: Calibration instructions are included in the user manual. They walk users through zeroing the device using supplied calibration materials to ensure that each test yields accurate and reliable results.
Q: What are the benefits of manual, hand-held operation?
A: Manual operation means no power supply is needed, offering greater mobility and simplicity. The immediate response and easy handling make it convenient for field and on-site assessments, helping streamline fruit quality control processes.
