If carton bearing a shockwatch label is dropped or roughly handled, Shockwatch reacts instantly. The liquid in the tube changes from clear to bright red, providing indisputable evidence that excessive impact has occurred. Normal movement or road shock won't activate Shockwatch - only the specific impact for which it was designed. Shockwatch labels utilize a very aggressive adhesive.
All components are relatively unaffected by moisture or normal temperatures.
Once activated, Shockwatch cannot be reset.
