GER1500 Underwater housing
Features
The Facility has recently bought an underwater housing for use with our GER1500s. It is rated to a depth of 40m. Inside the housing the GER1500 is aligned to allow both the lens and the laser to be seen through the field of view window. The laser is used to align target and panel measurements underwater. The GER1500 is operated using a rotary switch with push button control on the back of the housing, to alter the instrument settings. It is possible to change all instrument settings once the GER1500 is inside the underwater housing without having to remove it. The LCD display on the instrument can be seen clearly through the rear end plate. A remote trigger pigtail can be positioned either side of the instrument to take target and reference measurements. The system is sealed with "O" ring seals and overcentre latches to make the housing water tight.
Inside the housing, the instrument is run in stand alone mode which allows the operator to take up to 500 individual scans on its on-board memory. The instrument is run off a 2.2 aH, 12V gel battery which is mounted on a plate and fits inside the housing. The rear end plate has a download port so that a computer can be attached to download data, without removing the instrument from the housing.
