Static Coefficient of Friction Tester

825A SCOF Tribometer Kit

Our 825A meter, starting as the 725, was originally designed to match the C1028 50 lb. drag sled results. We did not copy it because of downfalls to the 50 lb. unit. Size, weight, and a large square Neolite pad that is prone to adhesion and other items. Over the years we have evolved and our meter has changed with the times and will continue to do so to always be reaching for the goal of being the best SCOF meter on the market. Our ever increasing customer base worldwide indicates that SCOF testing is not going away.

The 825A tests to the ANSI/NFSI B101.1-2009 and is shipped as a complete kit with all accessories included. It is also shipped as one meter of the combo DCOF and SCOF kit.



Easy To Calibrate, Easy to Use

Simple to follow instructions. Perform test in seconds. Designed for ease of operation and handling. Lightweight, complete kit is less than 8 lbs.



One year full manufacture warranty. Precision machined base and parts. Protective powder coat finish. Gage manufactured to plus/minus 1% accuracy. Tested and calibrated prior to shipping.


It is very simple to operate as you can see from the video. There is a quick hanging calibration that weighs the unit and then it is ready to use for dry or wet testing. When wet testing the dwell time that the meter sits on the wet surface prior to applying force should be kept to a minimal amount of time. One way is to lift up on the handle so the meter is just touching on the edge of 2 of the feet verses sitting flat, then just as you are ready to apply pressure, let the meter down, apply pressure to the meter by curling your finger in towards the palm of your hand while watching the front of the meter for forward movement, once the meter moves the static test is complete. Check the display for the results.

Reference Test Tile


Test materials referenced in various ASTM and ANSI/NFSI standards. Only takes a few seconds to calibrate while in the field. Display holds the high reading until recorded. The new ASM 825A model was designed to improve accuracy and repeatability for wet testing. The meters calibrate to the NFSI test tile wet. (NFSI tile only has a wet value) without adding calibration factors.
