American Slip Meter® has manufactured tribometers since 1993. Our meters are durable, reliable, repeatable, and fully supported. Floor safety programs and floor testing together equals safe floors. We now offer a dynamic coefficient of friction device, the ASM 925, in addition to our static coefficient of friction device, the ASM 825A. American Slip Meter®, Inc. has played a vital role in floor safety and manufacturing drag sled type slip meters, and we are actively involved in the ASTM, ANSI, and NFSI committees that develop and maintain walkway testing standards.
