The TRIAX TOUCH E-Missile is the latest evolution of playground surface impact testing devices. It is fully compliant with American (ASTM F1292), European (EN 1177), and many other worldwide standards for the measurement of shock (G) and head injury criteria (HIC) values as would be experienced during an impact of a head-on a surface system. Since 1988, continuous engineering development combined with ongoing participation in worldwide standards development has resulted in a device that produces accurate and consistent measurement results in both field and laboratory use.

Accurate and repeatable measurements require accurate fall heights, which are provided by TRIAX Tripod. Using the standard set of legs fall heights of up to 12 feet can be accommodated, extending to 14 feet with an optional additional set of leg sections. Snap together quick connect couplers for the tripod leg sections speed setup time allowing operators to get more work done in less time.

The collaboration of Alpha Automation and Canadian Playground Advisory has resulted in the advancement of standards for the protection of children at play and athletes around the world. A key element to the work behind TRIAX Touch is the provision of training, educational seminars, and participation in standards around the world.

The Triax Touch “E” missile system is intended to be used to measure the impact attenuation of surfaces under and around playground equipment in compliance with worldwide standards including but not limited to:

ASTM F1292

An upgrade program is available to allow owners of TRIAX 2000, TRIAX 2010, and TRIAX 2015 to the advantages of the wireless and touch screen display of the new TRIAX TOUCH. The existing tripod is re-manufactured to the TRIAX TOUCH functionality, and the existing accelerometer is re-calibrated and installed in a wireless head form. An upgrade includes a fresh calibration certificate. Note that the tripod legs are not upgraded

Pea gravel and loose stone surfaces are playground protective surfacing materials which present unique challenges requiring special accelerometers. Although pea gravel is becoming a very small portion of the entire playground protective surfacing market it is still found in some locales. Triax Impact testing devices can be fitted with optional specially designed accelerometers that can ensure reliable testing of pea gravel and loose stone surfaces. Should your playground inventory or inspection services include pea gravel, please consult with the factory prior to ordering.
