Enhanced measurement clarity: A acrylic sheet features a clear measurement grid with precise markings, enabling accurate crack monitoring and easy readability. Efficient monitoring solution: The simple analog design provides reliable detection of horizontal and vertical movements, delivering stable readings for long term monitoring. Accurate data recording: Two removable pins allow adjustable setup; movement is recorded on the chart and by the cursor for consistent crack observation. Dependable wall analysis: Manual 2D crack monitoring measures wall cracks consistently over time, supporting accurate and long term data collection. Key attributes and specifications Material: Acrylic sheet with a clear measurement grid Monitoring method: Manual 2D crack monitoring using chart and cursor Adjustability: Two removable pins for flexible setup Performance: Provides precise, reproducible readings for crack development over time Use scenarios construction inspections: Monitor earlyage cracks in poured concrete walls during curing to detect development patterns and ensure tolerance levels are not exceeded. Postevent structural checks: Track crack progression after earthquakes, heavy construction activity, or temperature cycling to assess structural impact and stability. Ongoing facility maintenance: Conduct regular wall crack surveys on commercial or industrial buildings to maintain longterm records and inform remediation decisions. Benefits at a glance Clear, precise grid for accurate crack measurements Simple analog design for reliable, longterm readings Adjustable, trackable data recording with chart and cursor Consistent 2D wall crack assessment supporting durable data collection
