Extended measurement range to ±25 mm supports expansion-joint measurements and larger crack-widths typical of unreinforced masonry (URM) foundations and buildings (URB).

Convenient integrated caliper standoffs improve measurement discrimination by a factor of 10 or more when using a quality digital calipers, such as Mitutoyo®, Starrett® or similar. Calipers are not included and must be purchased separately.
