• All electronic instrumentation is state of the art and the user friendly, menu-driven Windows® software, which allows the operator to enter and document multiple test parameters. The on-board laptop computer computes the Skid Number (SN) and the Peak Braking Coefficient (PBC) from the two-axis force transducer in real time. Data is stored for future analysis

  • Additional software capabilities include automatic system calibration, full system diagnostics, adjustable test cycle timing.

  • The system is equipped with digital encoders to accurately measure distance and monitor test speeds, a hand remote switch to initiate the automatic test, an industrial rated PC and graphic printer.

  • The operator can display all test results, both graphically and numerically. The computer automatically controls all phases of the testing cycle. 

  • The system software includes Calibration which allows the operator to calibrate the two-axis force transducer. The system’s computer calculates the gain and offset values for the force transducer and graphically displays the results.



The 995 Tire Traction Tester measures the peak friction characteristics on paved surfaces and it is used for tire testing to evaluate the dry or self-wetted friction characteristics of tires.

The 995 consists of a fully instrumented tow vehicle and test trailer, that uses a Dynatest two-axis force transducer to provide vertical load and horizontal tractive force measurements. As a pavement measurement device, it meets all the requirements of ISO 23671 and 15222, for wet grip measurements of C1 and C2 tires, as well as standard ASTM-E274, and ASTM-F408.
