Key benefits Precise and repeatable crack evaluation The clear grid layout on acrylic provides precise markings to support detailed crack evaluation and consistent crack monitoring. Simple, dependable displacement tracking An uncomplicated analog mechanism enables reliable observation of horizontal and vertical displacements with proven efficiency. Flexible setup with clear data capture Two removable pins allow quick adjustment of the instrument, while the chart and cursor record movement for consistent crack observation. Effective 2D crack progression monitoring Manual 2D measurements capture progressive changes in wall cracks while maintaining steady observation over time. Product attributes Material: clear acrylic with a precision grid for accurate markings Function: crack monitoring and measurement Displacement tracking: horizontal and vertical Data recording: chart and cursor for movement history Setup: two removable pins for adjustable positioning Measurement method: manual 2D crack tracking Design emphasis: gridbased layout to aid consistency and repeatability Compatibility: designed to work with standard crack monitoring practices and reference charts Use scenarios Residential or commercial wall crack surveillance Install the monitor on exterior or interior walls to track or existing cracks during renovations, weather events, or seismic activity. The grid aids repeatable readings, while the chart records progression for reporting. Long term foundation and retaining wall monitoring Place the device to observe slow shifts in foundations or retaining structures. The 2D manual measurements and removable pins enable flexible positioning and ongoing data collection for stability assessment. Construction quality control and load testing Use during construction or load testing to document crack development and verify structural response. The analog mechanism provides a straightforward, lowmaintenance method for frequent readings and quick decision support. Notes on use The tool emphasizes function, material quality, and straightforward operation to deliver reliable crack tracking without complex electronics. Suitable for environments where a simple, durable, and repeatable crack monitoring solution is preferred over electronic systems. Helps users demonstrate progression trends over time with clear, verifiable data from chart and cursor readings.
