Precision marking feature The device uses a precise measurement grid on robust acrylic to provide accurate markings for crack inspection and monitoring. This supports reliable tracking of crack position and progression. Simple analog tool Designed as an easytouse analog crack monitor, it enables accurate tracking of horizontal and vertical shifts with straightforward operation in a variety of environments. Dependable tracking mechanism Measurements are recorded on a chart using two removable pins, with a cursor that indicates movement for clear, dependable crack analysis. Dependable wall analysis Manual 2D crack monitoring allows consistent measurement of wall cracks over time, delivering accurate, longterm data.
