Cygnus 4 - General Purpose
Multiple Echo Ultrasonic Thickness Gauge
A compact general purpose Ultrasonic Thickness gauge gives accurate, error-checked, through-coating measurements using our Multiple Echo technology. Highly versatile for use in most hand-held industrial or shipping applications. The LCD display is easily read outdoors and perfect for use in all light conditions, with automatic white back light control. Menu-driven operation and "Deep-Coat" mode allow easy thickness gauging through coatings up to 20 mm. Cygnus 4, supplied in an IP65 rated/sealed aluminum enclosure, protective silicon sleeve and optional belt/harness clip is extremely light, tough and simple to use.
