Overview
Enviro Test Construct High Quallity Industrial Welding Crack Detectors can quickly, easily and without damage, accurately detect, locate, evaluate and diagnose various defects inside the workpiece such as cracks, welds, pores, sand holes, inclusions, folding, etc. It has been applied for electric power, petrochemical, boiler and pressure vessel, steel structure, military, aerospace, railway transportation, automobile, machinery, and other fields. It is an essential instrument for the non-destructive testing industry.
Features
- Measurement display mode: positive wave, negative wave, full wave, and Radio frequency wave.
- It has a linear suppression function; the maximum inhibition is 80% of the screen height.
- It can switch between single crystal probe, double crystal probe and two inspection modes.
- It has a gate setting and alarm function. The position and width of the gate can be arbitrarily set on the screen, and an incoming wave alarm can be set.
- Five hundred (500) independent detection channels, each channel set a separate set of testing parameters, DAC curve.
- Two display modes with angle and K value.
- The DAC curve is generated automatically, and up to 10 points can be recorded, with four additional adjustable offset curves.
- AVG curve is generated automatically, and two types of defects can be customized.
- Automatic probe calibration function.
- With storage function, it can store 100 A sweep patterns, parameters and DAC curve.
- Has a storage graphics playback function, stored A-scan graphics from the storage area and displayed on the screen.
- Has a delete function to delete the specified content (represented by the storage group number) from the storage area.
- Peak memory function.
- Freeze and thaw functions with waveform and inspection parameters.
- With sound path measurement and echo frequency analysis function.
- Real-time power status indication function.
- Support USB communication interface.
- Li-battery, low power consumption, can continuous working more than ten hours
- Can set up buzzer alarm during operation.
- Light, convenient, easy to operate.
