'''Shock Indicator''' is a mechanical device that detects and records mechanical shocks experienced by it. It is a common practice to attach shock indicators to expensive goods that are to be shipped.This way, the magnitude and the time of shocks are recorded to ensure that delicate and expensive instruments are not mishandled or exposed to inappropriate environmental conditions during shipping. The shock indicator provides a visual indication whether the shock threshold has been reached or exceeded, e.g. in the form of a broken spring or a digital display. | '''Shock Indicator''' is a mechanical device that detects and records mechanical shocks experienced by it.

Modern indicators that rely heavily on their supporting electronics are much more complex than their mechanical counterparts.They can not only detect and measure the shock, but also record the entire spectrum of shocks experienced over a period of several months or even years. They sometimes involve piezo-based[[ Accelerometers ]]with low consumption of electrical power. | Modern indicators that rely heavily on their supporting electronics are much more complex than their mechanical counterparts.They can not only detect and measure the shock, but also record the entire spectrum of shocks experienced over a period of several months or even years.
