impact test machina pro plastic adhibetur ad determinare impulsum spissitudo non-metallicae materiae ut plastic, auctus nylon, vitreum alimentorum fibra aucti plastici, LATERAMEN, lapis, plastic electrica adjumenta, et insulating materiae. Pendulum impulsum machina probatio communis est instrumentum ad qualitatem inspectionem per unitates scientificas inquisitionis, collegia et universitates, et non-metallicis materialibus artifices. Apparatus est simplex structura, facile ad operari, and high precision instrument. The digital display impact testing machine adopts high precision. Encoder technology has the characteristics of high accuracy, good stability and large measuring range. The digital measurement shows the impact strength and average value, the energy loss is automatically corrected, and the test report is printed.
