| Measuring Modes |
Multiple-Echo (three back-wall echoes) using Single Crystal (zero-degree) probes automatically ignores surface coatings and measures only metal thickness
Echo-Echo (two back-wall echos) using Twin Crystal probes
Single-Echo (first back-wall echo) using Twin Crystal probes |
| Accuracy |
±0.1 mm (±0.004”) or 0.1% of thickness measurement, whichever is greatest, when calibrated in accordance with Cygnus Instruments calibration procedure |
| Deep Coat |
In Multiple-Echo mode, allows measurement to be made through thicker coatings of suitable materials of up to 20 mm thick |
| Measurement Ranges |
Multiple-Echo (through coatings) with Single Crystal probes:
- 2.25 MHz = 3.0 to 250 mm
- 3.5 MHz = 2.0 to 150 mm
- 5.0 MHz = 1.0 to 50 mm
Echo-Echo with Twin Crystal probes:
- 5.0 MHz = 4.0 to 50 mm in steel
- 2.0 MHz = 6.0 to 50mm in steel
Single-Echo with Twin Crystal probes:
- 5.0 MHz = 2.0 to 100 mm in steel
- 2.0 MHz = 3.0 to 150 mm in steel
