The ShockWatch labels contain a tube filled with red liquid held in suspension. When the device is subjected to an impact exceeding a specified G-level, the shock disrupts the surface tension of the liquid, releasing the highly visible red dye into the length of the tube — creating a permanent and immediate indication of mishandling. Normal movement or road shock won’t affect the device — only the specific impacts for which it is designed. Once activated, the device cannot be reset.
The Lamerholm ShockWatch labels can be affixed to product packaging or directly onto the product itself, giving you the flexibility to prevent damage on virtually all goods requiring care during shipping and handling and the use of these devices can help to prevent warranty abuse.
Available in five sensitivities, as indicated by the five different colours — simply match the sensitivity of the label to the level of impact the product and packaging can withstand. Activation indicates an impact beyond the predetermined level.
