CK2108 Ultrasonic Flaw Detector
The CK2108 is a portable handheld ultrasonic flaw detector designed for rapid, accurate detection and evaluation of internal defects in metal components. It uses industrial-grade square wave excitation technology and operates in both single and double modes. The device supports a wide range of frequencies, pulse widths, and sound speeds, enabling reliable inspection in field and laboratory environments. Its high-resolution display and long battery life allow continuous use in remote or outdoor locations.
- Detects cracks, inclusions, folds, pores, and sand holes in metal workpieces without damage
- Operates in both single and double mode for flexible inspection setups
- High-resolution 5.7-inch TFT screen visible in direct sunlight
- Battery supports up to 8 to 11 hours of continuous operation
- Lightweight at 1.5 kg, suitable for handheld use in field inspections
- Field upgradable firmware for long-term usability and feature updates
Problems It Solves
- Manual inspection methods miss internal defects such as cracks and inclusions
- Heavy or non-portable equipment limits mobility in remote or hard-to-reach areas
- Low-resolution displays reduce visibility in bright outdoor conditions
- Short battery life forces frequent recharging during long inspection shifts
- Lack of field upgradability reduces device lifespan and adaptability

How It Is Operated
Power on the device and verify battery level
Select the appropriate material sound speed from the built-in list or enter custom value
Set pulse width, frequency, and gain based on the material and defect type
Position the probe on the test surface and initiate scanning
Monitor A-scan display and alarm signals for defect indications
Quality Control
- Device performance verified against standard linear error and sensitivity balance
- All calibration parameters tested within factory specifications
- Field upgradability ensures consistent performance over time
Customization Options
- Firmware can be updated in the field to adapt to new inspection standards
- User interface settings can be adjusted for specific inspection workflows
- Probe interface and cable types can be matched to existing probe inventory
How It Compares With Other Options
| RT10-C hand push trolley | The trolley covers longer track sections at 5 km/h but requires two people and track access; the CK2108 is handheld and faster for spot checks |
|---|---|
| UR18-D dual rail vehicle | The vehicle inspects both rails at 15 km/h over long distances; the CK2108 is for localized inspection of components, welds, or rails at a fixed point |
| GT6600 hi-rail vehicle | The hi-rail vehicle operates at 40 km/h on roads and rails; the CK2108 is portable and used for detailed inspection where speed is not required |
Use Guide
- Check battery charge before starting field work
- Select the correct material sound speed before each inspection
- Verify probe coupling and surface condition to avoid false signals
- Use the inhibition function to reduce background noise in high-interference environments
- Back up inspection data via USB after each session to prevent loss
