Scratch-A-Track Motion Monitor

Model: HM-642
$22.0000
Price: $22.00

This simple device provides a clear, continuous graphic record of total relative movement of adjacent surfaces. Whether it is mounted over a crack, joint or other void, the Monitor tracks thermal movement, structural settlement, load-induced deflections, or any other change in relative positioning. The unit is small, lightweight, inexpensive and weather resistant.

The plastic single-use Recording Pad has a target area coated with a white film and convenient blanks to record written data such as date, location, etc. The Pad is bonded to one surface using super-glue or epoxy (not included). The nickel coated spring steel Finger assembly is then bonded to the opposing surface and adjusted with a thumb screw so that the stainless steel Scriber moves over the surface of the Pad, it leaves a thin, well-defined black scratch to permanently record its movement. Finger and Scriber assembly may be used over and over.
