Model：PDI Shaft Quantitive Inspection Device (SQUID)
Country of Origin：USA, PDI
Use：A new technology for quantitative, real-time assessment of the cleanliness and competency of the bottom surface of bored pile or drilled shaft foundations.
Country of Origin：USA
Use：A cost effective QA testing device providing a visual representation of foundation excavation prior to concrete pour in wet conditions Wireless acquisition calculations of shaft profile to determine shaft radius, volume and verticality, 360 degree, 2D and 3D profile views Data acquisition at a rate of approximately one scan per second with eight channels scanned simultaneously Quick connection to Kelly bar or can be used with a top mount winch system
