This device uses Multiple-Echo mode to provide repeatable and reliable results by utilising three return echoes for greater accuracy. Capable of ±0.1 mm (±0.004”) or 0.1% of thickness measurement (whichever is greatest when calibrated in-line with our calibration procedures), this device also boasts a resolution of 0.1mm or 0.05 mm (both can be selected).

Finally, the Cygnus 1 is supplied with a protective case and two rechargeable batteries. Up to 10 hours of continuous testing can be achieved on a single battery.


Cygnus Dive Underwater Gauge

For underwater testing, you need the Cygnus Dive Underwater Gauge. The impressively large and bright 2.8” AMOLED display features quarter VGA colour, 320 x 240 pixels, 15mm high numbers, A-Scan display with automatic X axis and tool and is viewable from all angles. Sporting Multiple-Echo, Echo-Echo and Single-Echo modes, this device offers a wide range of resolutions and measurement ranges.

With the Multiple-Echo mode, this device will work with coatings up to 20mm in thickness. Plus, the Cygnus Dive provides ±0.1 mm or 0.1% of thickness measurement, whichever is greatest, when calibrated in accordance with Cygnus Instruments calibration procedure.

Simple to operate, and depth rated to 300m, the Cygnus Dive also features an MSI™ Measurement Stability Indicator. Exclusive to Cygnus, this nifty little feature identifies a stable reading by shifting the colour of the numbers from red to yellow – only available in Single and Echo-Echo modes.


Twin Crystal Ultrasonic Probes

As mentioned earlier, it’s not just ultrasonic thickness gauges that we stock; we also supply ultrasonic probes too. Our Twin Crystal Ultrasonic Probes are ideally suited for use with ultrasonic thickness gauges that utilise Single or Echo-Echo modes. Featuring a two-sided face; one side transmits the ultrasonic energy and the other side receives it. These probes feature a hard wear face and the gauge will automatically compensate for any wear.

Once the probe has sustained excessive wear, a message prompts you to replace it. In Echo-Echo mode, each of these probes can ignore up to 1mm of coating. Specifications will vary from one probe to the next, but you can find out more by clicking on our Twin Crystal Ultrasonic Probe page.
