The Mark-10 M5-2-COF coefficient of friction (COF) gauge is an integral part of a COF testing system. With a capacity of 2 lbF [10 N], the gauge can be used to measure friction for a wide range of materials, ideal for conformance to ASTM D1894 and other relevant standards. Static and kinetic coefficients are displayed on the backlit LCD and are calculated from a user-programmable sled weight.
Data can be transferred to a PC or data collectors via USB, RS-232, Mitutoyo (Digimatic), or analog outputs. On-board memory for up to 1,000 readings is included, as are statistical calculations with output to a PC. Integrated set points with indicators and outputs are ideal for pass-fail testing and for triggering external devices such as an alarm, relay, or test stand. Configurable password protects against unauthorized changes to settings.
The M5-2-COF may also be used for several common tension and compression testing applications. The gauge is based on Mark-10's Series 5 advanced digital force gauges and includes the series' full set of functions and settings.
The M5-2-COF includes MESUR Lite data acquisition software. MESUR Lite tabulates continuous or single-point data. Data saved in the gauge's memory can also be downloaded in bulk. One-click export to Excel easily allows for further data manipulation. Available with or without the G1086 Fixture.
