Description
Overview
GAOTek Ultrasonic Concrete Flaw Scanner is the perfect device for cross-hole acoustic wave transmission method. This instrument is specifically designed for testing the pile foundation integrity by using acoustic a wave transmission method and contains the unique multi-channel self-emission/self-receiving function. It also enables the concrete pile all-profile test with only one lift (3 or 4 acoustic testing pipes embedded), which makes the detection process more efficient and simpler.
Features
- Fast testing with adjustable gains and delays
- Display 6-profile information on one screen
- Multiple testing modes for accurate defect identification
- Sturdy, waterproof carry case for durability and protection
