IST - Model HIRTS-1 - Helmet Impact Recording System - Brochure

The HIRTS-1 is a compact, self-contained recording device which measures and records shock and impact to helmets or other space constrained fixtures. The device is planted or installed to an inside surface of the helmet. The device contains three accelerometer sensors which accurately measure the accelerations (forces) during helmet impacts, in 3-directions. Therefore the device can measure and record impacts from any direction, and at any time. During an impact event the device measures and records the peak, or maximum, acceleration (force) of the event, in each of three axes (x, y, and z) along with the exact date and time of occurrence. In addition, the device measures and records the “change in velocity” (proportional to energy) associated with the impact acceleration event in each of three axes (x, y, and z).
