Description
Key Features of the Cygnus 4 General Purpose Meter
- Multiple-Echo mode for accurate, through-coat measurements as specified by Classification Societies
- Deep Coat function ignores coatings up to 0.8 inch (20 mm) thick
- Simple, one-point calibration – no zeroing required
- Min/Max measurement limit functions
- Visual and vibrate alert
- Intuitive easy to use menu
- Large and bright front color LCD display
- Extremely rugged enclosure – shock and impact proof to US MIL STD 810G
- Environmental sealing (water and dust proof) to IP67 – US MIL STD 810G
- Can be upgraded to 4+ or 6+ at an additional cost.
Cygnus-Pioneered Multiple Echo Technique
- Uses three return echoes to give a truly accurate, error-checked metal thickness measurement – ignoring coatings up to 0.8 inch (20 mm).
- Accepted by all the major Classification Societies.

To compliment our ultrasonic thickness gages we offer a range of ultrasonic transducers. The performance of any ultrasonic thickness gage relies heavily on the transducer and its suitability to the material being measured. Therefore, selecting the right transducer is vital. All Cygnus SINGLE CRYSTAL transducers are made from stainless steel and include replaceable membranes for long life, requiring no zeroing and have a high linear accuracy.
