The XL was engineered specifically for wet testing. It mimics certain biomechanical parameters of the human gait, unlike traditional slipmeters that tend to give misleading results in the presence of real-world environmental contaminants, due to disabling sticktion, a phenomenon arising from dragsled meters and others having residence time before the slip dynamics are applied.

Portable
The English XL Variable Incidence Tribometer is lighter than your laptop (3.85 pounds) and has a nicer carrying case, complete with shoulder strap. The XL slipmeter is the easiest-to-use of all tribometers. It comes as a complete slip resistance testing kit, including the most extensive documentation of any slipmeter available. Click here for a tutorial on using the XL Variable Incidence Tribometer. Advanced training leading to a certificate of competence is available for serious users who want to become expert.

Reliable
The XL is engineered so as to be capable of measuring the slipperiness of any floor surface, even when wet or contaminated with other lubricating spills. Because the research shows that no other slip resistance measurement device comes close to the XL's validity on wet or otherwise lubricated surfaces it has become the choice of experts. It is fully tested and calibrated before shipment and 100% unconditionally guaranteed for one full year.

Unique Advantages
The XL is really portable. It is the lightest-weight slipmeter available and can actually be carried onto an airplane with ease (it fits easily under the seat.) You won't need a handtruck to carry it around!

• It can be used on wet or oily surfaces with realistic results.
• It is direct reading. No calculations are required to interpret results.
• Being independent of gravity, it is the only slipmeter you can use on ramps without recalibration.
• It is the only slipmeter that can take traction readings on stair tread nosings parallel to the direction of pedestrian travel.
• It is completely self-contained. No power cords or batteries to charge.

Here's What You Get
The XL Variable Incidence Tribometer comes with everything you need to measure slip resistance: a deluxe soft-sides carrying case, stair fixture, four blank feet, sanding block, dust brush, water bottle and thorough documentation (including a copy of the current edition of Pedestrian Slip Resistance: How to Measure It and How to Improve It. at no extra charge). You will quickly learn how to use the XL competently by following fully illustrated instructions.

Standards Applicable to the XL
There are ANSI/ASTM/NFPA standards now in effect for using the English XL Variable Incidence Tribometer. Applicable standards currently in print and available include:

• ASTM F1679-04 Test Method for using a Variable Incidence Tribometer (English XL)
• NFPA 1901 Standard for Automotive Apparatus, 13-7.3
• ANSI A1264.2 Provision of slip Resistance in the Workplace

The XL is also acceptable for determining compliance with ADAAG for slip resistance on walking surfaces.

Affordable
For less than the cost of one falling accident you can have the ultimate slip/fall safety engineering tool. Acquisition cost may qualify for tax credits under the Americans with Disabilities Act.
