ShockWatch® 2 25G Indicators are single-use impact sensors that activate irreversibly when a package or product experiences a qualifying impact at or above 25G of force. Each 1-2/3" x 1-2/3" indicator features bi-directional vertical detection and turns bright red upon activation, providing an immediate, unambiguous visual record of mishandling. Activation requires only removing the adhesive liner for direct application to any surface.

These indicators are used in manufacturing, pharmaceuticals, electronics distribution, and logistics operations where fragile or high-value goods require documented handling accountability. They are equally effective on individual parcels, palletized freight, and sensitive equipment during both transit and warehousing.

Each unit carries a unique serial number to support tamper-evident chain-of-custody documentation. A companion label (3-3/4" x 3-3/4", sold separately) increases handler visibility and communicates response procedures; Alert Tape (sold separately) further signals that a shipment is monitored. Indicators are sold in cases of 50.
