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 the total relative movement of adjacent surfaces.

The Scratch-A-Track Motion Monitor is mounted over a crack, joint, or another void, and anchored with user-supplied concrete screws. When mounted, the spring steel finger and thumb screw assembly allow pressure to be applied for scribing onto the HM-643 Scratch-A-Track Monitor Recording Pads (purchased separately) for use.

Features:

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

Product Q&A

Q: Will this work with fan-forced heaters?

I'm very satisfied with this product. It was exactly what I wanted in my travel trailer, for a lot more accurate heating. Now I can pinpoint it to exactly the temperature I want, instead of guessing, sliding the conventional thermostat back and forth. Will for sure save on propane too! Nice back light when adjusting the temperature, making it easy to see even at night.
