Peter Ermish is President of Regan Scientific Instruments, Inc. , LP, Southlake, TX. Regan Scientific (RSI) manufactures the Binary Output Tribometer or BOT-3000, a portable robotic device for both laboratory and on-site testing of dry and wet, static and dynamic, coefficient of friction (COF). Since the BOT is an automated unit that can be validated in the field, user error or variability is minimized. The BOT is approved by the National Floor Safety Institute, the Tile Council of North America, and the Concrete Polishers Association of America for use with their respective COF standards. It is also recommended by a major insurance carrier, and other expert groups.
