The Cygnus Mini ROV Mountable thickness gauge has been specially designed to be mounted onto small observation ROVs with or without a manipulator facility. Built-in conjunction with VideoRay, this mountable subsea thickness gauge will allow the operator to carry out an ultrasonic thickness measurement in areas that have previously been unfeasible using larger ROVs or divers. The multiple echo thickness gauge measures metal thickness and corrosion without removing protective coatings. Dedicated software displays the time, date and thickness readings on the surface which can all be stored or logged. Alternatively, an optional Topside Repeater (TSR) is available which has the facility to display the thickness measurements remotely and overlay them on to a video signal. This allows the measurements to be superimposed on the ROV camera™s monitor screen. The unit is pressure tested to 1,640 ft (500 m). Features: Designed specifically to mount onto small observation ROV™s. Supplied with *CygLink software to display and log thickness measurements from the ROV on a computer at the surface which can be saved to a file and printed out. CygLink has two data logging facilities: Quick Log for simple recording of thickness measurements and structured mode with four templates available “ Single Point, Multi Point, Grid Point and KeyPoint. Easy calibration at the surface via CygLink software or Top Side Repeater (TSR) unit. Optional dedicated probe holder to allow measurements on curved or flat surfaces. Only one twisted pair is required to transfer the data to the surface.

The Riken Keiki RX-515, RX-516, RX-517 marine portable combination gas detectors are specially designed and developed for marine applications. When loading tanks are flushed with inert gases, the O2 content drops proportionally to some inert gases used. Catalytic EX sensors need a minimum content of oxygen in the sample gas to be able to measure combustible gases correctly. As this minimum content is not available, instruments with catalytic sensors are not suitable for conducting EX measurements in inert atmospheres. A solution to this problem is to use infrared technology sensors (NDIR). Infrared sensors measure concentrations of combustible gases reliably, even if O2 is not present. With the Riken Keiki RX-515, RX-516 or RX-517 and, its NDIR sensor you are well suited for this kind of application.
