|
| Battery |
Single 3.6V Li-ion 8.2 W battery
11 hours continuous measurement
Low battery warning ‘alert’ message
|
| Measurement 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
|
| Deep Coat | In Multiple-Echo mode, allows measurement to be made through thicker coatings of suitable materials of up to 20 mm thick |
| Accuracy | ±0.1 mm (±0.004”) or 0.1% of thickness measurement, whichever is greatest, when calibrated in accordance with Cygnus Instruments calibration procedure |
| Probe Cables |
Double outer jacket in tough PU. Coloured yellow for easy
locations underwater. Coiled for ease of use. Fischer S105 series
connectors.

| 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
|
| Measurement Resolution |
0.1 mm – Low resolution mode or measurement >99.95 mm
0.05 mm – High resolution mode and measurement <100.0 mm
0.01 mm – Single-Echo mode only and measurement <100.0 mm
