The AELAB Fruit Hardness Tester FHT-05 is a compact digital penetrometer designed for fruit and vegetable hardness testing. By measuring the force required to penetrate fruit pulp, the instrument assists in determining ripeness, picking time, and monitoring softening during storage. The FHT Series provides Max, Hold, and unit conversion functions to support field use and laboratory quality-control workflows.
With USB/RS-232 data output and optional Bluetooth connectivity, the FHT-05 enables seamless transfer of firmness measurements to PC software for analysis and reporting.
The AELAB FHT-05 features a durable handheld structure with a 3.5 mm penetration tip engineered for consistent hardness measurement across soft, small, firm, and hard fruits. The digital display ensures clear reading of force values, while the ergonomic body supports stable pressing motion. The 10 mm pressing depth is optimized for standardized agricultural firmness testing.
The FHT-05 quantifies fruit hardness by measuring the penetration force when the 3.5 mm tip plunges into fruit pulp. The internal load cell detects resistance and converts it into kgf/cm², lbf/cm², N/cm², or Pa. The data output allows continuous monitoring of ripening, quality grading, and softening curves. The device maintains measurement stability across 0~45 °C with humidity below 90%RH.
The FHT-05 supports RS-232C data cable connection for PC software integration. Data can also be transmitted via optional Bluetooth adapter for wireless acquisition. The unit is compatible with AELAB analysis software for storage, trending, and reporting of firmness measurements.
The FHT Series includes classifications for different fruit groups based on pulp firmness. Below is the catalog-verified classification table:
| Fruit | Example |
|---|---|
| Small Fruit | Strawberry, Cherry, Grape, Berry |
| Soft Fruit | Peach, Banana, Apricot, Plum, Melon, Citrus, Persimmon |
| Firm Fruit | Pear, Nectarine, Kiwi |
| Hard Fruit | Avocado |
The AELAB FHT-05 is used in orchards, packing houses, research centers, and food-quality laboratories. Typical applications include monitoring fruit maturity, assessing readiness for harvesting, controlling postharvest softening, and evaluating varietal firmness characteristics for breeding programs.
The instrument is manufactured under AELAB quality standards with traceable calibration procedures. It supports Good Laboratory Practice (GLP) documentation through digital data export and standardized measurement protocols.
