Description
large-format differential-displacement scientific instrument for measurements of wide cracks, fissures, and expansion joints. A large 160-mm (-55 to +105 mm) measurement range with a unique offset scale supports peak-to-peak differential motion displacement of 160 mm on the X (horizontal) axis and 40 mm on the Y (vertical) axis.
Extreme Measurement Range: 150 mm (X) and 40 mm (Y)
Rugged: Heavy-duty, crystal-clear polymer will not yellow
