HTHY PSRT-2

This laboratory instrument applies the Wehner/Schulze method to accurately measure post-polish friction on asphalt, concrete, and other material samples.It accommodates samples of various sizes to realistically simulate tire-road skid resistance behavior. The system's testing technology has been aligned with international industry standards while maintaining the original measurement principle.
FEATURES  
   -The use of stainless steel provides excellent corrosion resistance and extends the service life of the equipment.
   -The test chamber is equipped with an acrylic protective cover to prevent water splashing while allowing clear observation of the experimental process.
   -The four-station design facilitates convenient operation and improves efficiency.
   -An independent calibration station avoids operational errors caused by repeated installation of standard reference plates.
   -An upgraded mixer and water pump are used for mixing and pumping abrasive materials, enhancing experimental efficiency.
   -The main skid resistance measurement platform incorporates a high-precision torque measurement system and a fully automated testing program, enabling more convenient and accurate wear and skid resistance performance testing.
   -A new corrosion-resistant temperature control system ensures precise and reliable temperature management during experiments.
   -The equipment supports programmable test processes, including polishing, cleaning, and measurement, improving experimental flexibility and accuracy.
   -It is equipped with a high-quality industrial controller with a touchscreen and graphical display, allowing simultaneous monitoring of measured values and the testing process,while providing multiple control modes and functions with graphical output.
