M5-2-COF Coefficient Of Friction Gauge
The M5-2-COF coefficient of friction (COF) gauge is an integral part of a COF testing system, typically including a motorized test stand and G1086 COF fixture.
This G1086 COF fixture is an integral part of a COF measurement system, typically including a motorized test stand and COF gauge. The G1086 can be used for a wide range of materials, ideal for conformance to ASTM D1894 and other relevant standards. Static and kinetic coefficients can be measured using the M5-2-COF gauge.
The fixture includes a large work table with sample clamp, level, 200 g sled, cable, and low-friction pulley. The fixture is directly compatible with the M5-2-COF gauge, and the ESM303 motorized test stand.
With a capacity of 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 a number of common tension and compression testing applications. The gauge is based on 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.
