BOT 3000E Regan scientific instruments logo


The BOT-3000E (Binary Output Tribometer) manufactured by Regan Scientific Instruments, is a highly precise, digital instrument capable of measuring the dynamic and static coefficient of friction (COF) of walkway surfaces in the lab and in the field. The BOT-3000E is used worldwide and has become the industry accepted tribometer of choice. The device can measure both static and dynamic coefficient of friction with a variety of test sliders in both wet and dry conditions.

It is the only device qualified for use with ANSI A326.3 “American National Standard Test Method for Measuring Dynamic Coefficient of Friction of Hard Surface Flooring Materials” released in April 2017. It meets the requirements of ASTM 2508 for the validation and certification of walkway tribometers, as tested by an independent laboratory. Measuring walkway slip resistance with the BOT-3000E per the ANSI A326.3 method allows you to recognize and remove slip and fall hazards, in compliance with the Standard of Care called for in OSHA Section 5(a)(1), General Duty Clause. The BOT-3000E is the only tribometer that has a data collecting and reporting app (STEP) that conforms to ANSI and ASTM standards. The device performs a test without human input except for the pressing of a button, making it more difficult for the operator to manipulate the results of the test.


The BOT-3000E and ANSI 326.3 are the results of published research conducted in the United States and Germany and represent the sound scientific methodology required to meet the “Daubert” rule of evidence in United States federal and state courts. The device is a motorized drag-sled which moves at a constant velocity along the floor surface. While moving, the slip resistance is metered and recorded via a standardized rubber sensing module in contact with the floor.

The BOT-3000E Tribometer is capable of measuring the Coefficient of Friction, both wet and dry, of most hard surface floors, including but not limited to:
  • Ceramic and porcelain floor tiles
  • Marble floor tiles
  • Travertine floor tiles
  • Granite floor tiles
  • Limestone floor tiles
  • Polished concrete flooring (Industrial and decorative)
  • Terrazzo flooring (epoxy and cement based)
  • Engineered stone tiles
  • Quarry tile
  • VCT Tile
  • LVT and other resilient surfaces


At Stop Slip Solutions we can provide in-field Coefficient of Friction (COF) testing on all hard walkway surfaces. We test to the American National Standard (ANSI) A326.3, “Test Method for Measuring Dynamic Coefficient of Friction of Hard Surface Flooring Materials.” Stop Slip Solutions uses the RSI BOT-3000E Tribometer, the only device approved for use with ANSI A326.3. Use our slip test services to validate COF values on new floor surfaces prior to occupancy, to monitor the effect of maintenance and pedestrian traffic on available slip resistance, and to measure the effectiveness of floor care products. Upon completion of the in-field testing an audit report will be prepared in accordance with the ASTM F1694-14, “Standard Guide For Composing Walkway Surface Investigation, Evaluation, and Incident Report Forms for Slips, Stumbles, Trips, and Falls,” and the ASTM F2048-00, “Standard Practice for Reporting Slip Resistance Test Results.” The audit report will include:
  • A testing diagram with test location(s) and testing conditions identified
  • A description of the hard surface flooring conditions, as per astm standards
  • An executive summary of “ansi a326.3 american national standard test method for measuring dynamic coefficient of friction of hard surface flooring materials.”
  • All dcof measurements and a statistical analysis of dcof results
  • Tribometer reports which include a timestamp, a date stamp, photos, and graphs of each individual dcof sample.
