Dart Impact Tester - Prima Model

Presto's Dart Impact Tester - HMI stands as a premium testing instrument widely utilized across diverse packaging industries for evaluating the resilience of plastic films against various applied forces. The device features an electromagnetic dart hold/release mechanism, ensuring uninterrupted force application. Capable of securely holding weights up to 2 kg, this mechanism adds to the instrument's reliability. The user-friendly HMI display facilitates the easy determination of the number of falls executed in a single test.

Simplified sample handling is achieved through a foot switch, allowing convenient clamping or unclamping. The machine is equipped with pneumatic clamping, ensuring the wrinkle-free fixation of the test specimen. To prevent dart rebound upon impact, a shielding device is incorporated into the machine, enhancing safety and precision in testing.
