Three-model analog fruit penetrometer (GY-1 / GY-2 / GY-3) for fast, reliable fruit firmness and maturity testing.

The GY Series analog fruit hardness tester (also called fruit penetrometer or sclerometer) includes three models: GY-1, GY-2 and GY-3, designed specially for inspecting the hardness of fruits such as apple, pear, strawberry, grape and so on. Judging the hardness and maturity of fruits helps with breeding, storage, export, transport and processing.

With measuring ranges from 0.5 to 24 kg/cm² across the series, a compact pen-style body of 140×60×30 mm and a weight of only 0.5 kg, the GY series fruit firmness testers are widely used by fruit research departments, fruit companies, fruit farms, colleges and similar organizations for daily fruit quality control.
