The TRIAX Touch A-MISSILE system is the latest evolution of the TRIAX family of playing surface impact test systems that is wireless and fully compliant with the ASTM F355 procedure. A standard for the measurement of shock (Gmax) values since 1988, continuous engineering development, combined with ongoing participation in worldwide standards equipment has resulted in a device that produces accurate and consistent results in both field and laboratory use.

The TRIAX Touch A-MISSILE system features a precision-machined aluminum guide tube with a quick attach base plate. This design quickly ensures the 24” drop height and disassembles for easy transport. The sturdy manual release mechanism holds the missile until the operator pulls back on the knob, releasing the missile allowing it to impact the test surface.

The Triax Touch “A” missile system is intended to measure the impact attenuation of artificial and natural turf playing surfaces in compliance with standards including but not limited to:

ASTM F1936


ASTM F1081

ASTM F2970
