Accurate Friction Testing for Packaging Materials

The instrument is tailored for measuring both static and kinetic coefficients of friction for stretch wrap films and similar substrates. Its mirror-finish stainless steel sled and factory calibration ensure high precision and compliance with ASTM D1894. The device's robust laboratory-grade build and adjustable test speed offer flexibility for diverse testing requirements.


User-Friendly Operation with Automated Controls

The instrument features digital LCD display and microprocessor-based automation, streamlining the testing process. Operators can easily adjust test speed (100-500 mm/min), monitor live readings, and analyze results using the provided Windows software. Safety mechanisms, including emergency stop and overload protection, ensure secure operation throughout testing.


Advanced Data Management and Output Options

Test results are efficiently managed with integrated software support for Windows systems. Data can be stored, printed, or exported in .csv format, allowing for seamless integration into laboratory management workflows. The instrument supports both RS232 and USB interfaces for versatile connectivity.
