FIFA Impact Tester with Clegg Hammer Equivalents

The FieldTester (3A Model) v4 FIFA Impact Tester is a compact, lightweight device designed to evaluate the safety, uniformity, and playability of natural grass and synthetic turf sports fields. It measures key surface properties such as force reduction, vertical deformation, and energy restitution, while also providing Clegg Hammer equivalent values (CIST/gMax). This tool complies with FIFA and CEN/TS testing standards, making it suitable for multiple sports including football, soccer, baseball, softball, lacrosse, and polo.

Equipped with a universal axial speed sensor and wireless app compatibility for iOS devices, the FieldTester offers fast and precise results. Tests are recorded and displayed instantly on the included iPod, providing convenient access to data on the spot. Weighing just 22 lbs (10 kg), it is highly portable and easy to operate, allowing for quick testing across different fields.

This tester is valuable not only for professional labs but also for sports field installers, maintenance crews, municipalities, clubs, and coaches to ensure surface quality meets safety and performance expectations. Key measured parameters include:

• Force Reduction: Percentage of shock absorption compared to concrete (0%), assessing surface comfort and injury risk.

• Vertical Deformation: Measures the surface’s vertical compression under impact, indicating stability and firmness.

• Energy Restitution: Percentage of energy returned to athletes, reflecting surface responsiveness.

Powered by a rechargeable battery, the FieldTester combines precision laboratory measurements with field portability and user-friendly design. It supports maintaining consistent player-surface interactions and adherence to international sports surface safety guidelines.
