1. CYGNUS S INSTRUMENTS DIVE MULTIPLE ECHO ULTRASONIC DIGITAL THICKNESS GAUGE Measures metal thickness to determine wastage or corrosion accurately quickly and without removing protective coatings Features The latest innovation from the pioneers of the digital multiple echo ultrasonic thickness gauge the Cygnus DIVE is designed for the professional diver and is accurate reliable and easy to use Worn on the diver s forearm it gives an invaluable free hand while performing thickness surveys Made from a tough glass filled resin the Cygnus DIVE can withstand the knocks and bumps of the diving environment A large bright colour TFT screen displays the thickness measurements in big numbers that really stand out choose the display colour that suits you Simple Operation Like all Cygnus products the Cygnus DIVE has been designed for easy operation There are no gates to set up no gain to adjust justturn on and go There are two buttons for quick and easy menu navigation using one hand from here you can access all the functions of the gauge guided by intuitive clear menus Rechargeable Batteries Power is supplied by a replaceable rechargeable Lithium lon battery pack that gives up to 10 hours continuous operation Measurement Technology The Cygnus DIVE uses the trusted Multiple Echo Technique first developed by Cygnus over 25 years ago With minimal surface preparation the Cygnus DIVE will measure metal thickness throu2. d thickness measurements as part of a thickness survey The operator can choose to log the thickness measurements taken by the diver or using the A Scan graph estimate the thickness and record this value instead useful when gauging on heavy corrosion Instrument Status and Control DIVELink allows an operator to see the battery status of the Cygnus DIVE The material velocity unit and Deep Coat settings can also be changed from the surface wi fie Vew Proyect toute munis E varaos Wo coe on eenst voat m STMT GRID OLN ove mm STATAIL 120028 915 ave mm ALANLA WS mA ma LLANE SSi mm IIAL 130028 WIS mis me HLA Fini me TALMI Nani me IAAL 120037 WIS ny ma IAL oot imi pli mm AUMAIA SP E 3 ma TIEN 120048 Sed vy ssa a eu mom THAAI 120052 Se are ss sua SEF oals piiss Mimare Ciis iniii Need Egon Feee LOL Cowierion State Satter OE Semel No ODDA Gna ype Cyma Dea Aki Erho Minie Tnip r icio Deaprast Mode Ot Often divers face taking thickness measurement surveys in black or limited visibility water so Cygnus developed HelmetView A small remote display is mounted just in front of the lens on the diver s helmet using the accessory screw a short cable then plugs in to the Cygnus DIVE s top side data connector Thickness measurement values are then clearly visible to the diver even if they can t see any further Thickness measurements are clearly displayed on an OLED display and its brightness can be adjusted from
