Features

• Effortless Alignment with 2 Pre-Set Pegs: Unlike standard crack monitors, this updated version features two integrated pre-set pegs that allow you to instantly position and secure both sliding plates at the correct starting point. No more guessing or measuring during installation the pegs ensure accurate zero-position setup, saving time and eliminating user error
• Precise Crack Movement Monitoring: Measures crack opening and closing with 1mm (0.04") accuracy on X-Y axes. Discrimination down to 0.5mm (0.02") ensures reliable tracking of wall cracks over time. The pre-set pegs guarantee that initial readings are consistent across multiple monitors on the same structure
• Bidirectional Measurement: Tracks both horizontal (20mm / 0.79") and vertical (10mm / 0.38") movements. Ideal for monitoring structural shifts in concrete, brick, or drywall. The pre-set pegs maintain perfect orthogonal alignment, so diagonal crack movements are captured accurately without skew

The transparent top plate features a fine crosshair cursor, overlapping a millimeter-calibrated bottom plate for quick, accurate readings. The pre-set pegs are molded into the body no loose parts to lose or misplace
