Scratch-A-Track Motion Monitor

Model: HM-642
Price: $25.50

Scratch-A-Track Motion Monitor tracks thermal movement, structural settlement, load-induced deflections, and other changes in relative positioning. The monitor is compact, lightweight and weather-resistant, and designed to provide a clear, continuous graphic record of total relative movement of adjacent surfaces. Can be mounted over a crack, joint, or another void, and anchored with a user-supplied concrete screw, or an adhesive such as glue or epoxy.

The Scratch-A-Track Motion Monitor works with HM-643 Scratch-A-Track Monitor Recording Pads, plastic single-use recording pads that are bonded to the monitor surface with super-glue or epoxy to record data and create a permanent record of movement.


  • Small and weather-resistant
  • Easily mounted over cracks, joints or other voids
  • Creates a permanent record when used with recording pads
