Unidirectional Single Channel Shock Indicator SR-387


The Inertia Switch model SR-387 is a visual shock recorder that can monitor G level forces on a single axis. Once the predetermined G level has been exceeded, a ball will appear in the window. The unit can then easily be reset by pushing a button. Upon special request, tamper proof seals can be provided. These durable units can be made in one, two, four, or six channel modes. Please contact our engineering department for more details.
