Description
Overview
The GAO Tek ultrasonic flaw detector can quickly, non-destructively, and accurately detect various defects (cracks, inclusions, blowholes, etc.) inside the workpiece. The product is unique in design, easy to operate and durable. It adopts an all-English true-color liquid crystal display. Different color schemes can be selected according to the environment. The brightness of liquid crystal can be adjusted under strong outdoor light. Master-slave menu design, with digital shuttle wheel, easy to operate, leading technology.
Features
- High right electroluminescent, strength light, weak light and sunlight viewable
- 32 independent sets of parameters can be set.
- Large capacity Li battery
- Can be connected to the printer, print inspection report and wave.
- Has auto-calibration function for normal probe
- Square wave pulse generator can be adjusted, suitable to test the defects of work piece with different materials and depth.
