This feature can be used to record all testing in real-time.

The GS-1 measures both the static and dynamic coefficients of friction, providing an accurate measurement of surface slipperiness in both dry and wet conditions while taking multiple sequential measurements to ensure the highest level of accuracy and to produce an average slip coefficient value. It provides the raw data as well as automatically calculated findings can be saved and printed onto an 8.5 x 11 inch paper appropriate for written reports and courtroom presentations. The GS-1 relies upon unique, patent pending technology to seamlessly integrate a comprehensive range of features far beyond what other tribometers offer.
