CESM303-COF is a package for COF testing. All items that are needed to perform a COF test is included.

The speed of the COF test can be set in the ESM303 motorized test stand controller. This test stand has limit switches witch can be used to stop the cross-arm. Additional options can be added to the test stand if needed.

Static and kinetic coefficients are displayed on the backlit LCD of the M5-2-COF, and are calculated from a user-programmable sled weight.

The ESM303 motorized test stand can be used for a lot of different tests. This package with accessories is for COF testing. Additional force gauges, grips, fixtures and optional functions can be added for running other tests.

The M5-2-COF has a 2 lbf capacity, because COF forces are very low forces. If other tests will be performed you will likely need a higher capacity force gauge for those tests.

Static and kinetic coefficients are displayed on the backlit LCD of the M5-2-COF, and are calculated from a user-programmable sled weight.


ESM303 Features

  • Selectable speed setting 0.5 - 13 in/min (13 - 330 mm/min)
  • Upper and lower travel limit switches
  • Password protection of test parameters
  • Compact footprint, suitable for crowded workbenches
  • Stepper motor-driven, producing smooth and quiet operation with no speed variation under load

    M5-2-COF Features 

    The M5-2-COF performs COF calculations by dividing the force by the sled weight. For example, a force of 100 gF divided by 200 g equals 0.5 COF. Although many COF testing applications require a sled weight of 200 g, the gauge allows the user to change the sled weight to comply with other requirements. To modify the sled weight, select COF from the menu.
    Average mode is used to obtain an average force over time. This reading also represents the kinetic coefficient of friction for the M5-2-COF gauge. The minimum force required to start the averaging sequence. Initial delay follows the trigger force.
