Cracks monitoring spies allow to measure cracks and gaps and corners of a building/ceiling/floor and parallel walls. In comparison with totals stations and levels they accelerate measurements.

101-RS1 spy can be joined with a rotation adaptor 101-RS5 (optional) for measurements in corners or the area between a floor and a wall. Spies are made of an impact-resistant polycarbonate.

For almost parallel displacement TT4 spy is recommended.
