Vacuum Leak Test Systems
-
Vacuum leak testing is the principal leak test method for testing parts that could have leakage from an external source into their housings and casings. Parts like underwater sensors or housings, outdoor electrical housings, sealed components, and components associated with vacuum sources are all prime candidates for vacuum leak testing. Operation of instruments that supply vacuum to test parts instead of pressure works in a similar, yet essentially opposite, manner as pressure decay testing.

AUV | ROV Sensors: AUV | ROV Sensors
-
Autonomous and remotely operated underwater vehicles are rapidly evolving to fill scientific niches, many with capabilities otherwise unattainable through traditional manned research at a fraction of the operating cost. Sea-Bird Scientific offers a line of sensors uniquely designed for integration with various unmanned underwater vehicles, expanding data potential and opening new doors for unique research opportunities. While Sea-Bird Scientific originally designed most sensors for stand-alone applications, we have redesigned and miniaturized popular product lines meet the specific operational requirements of unmanned research platforms: a 1 kg CTD can now replace a 10 kg CTD while maintaining the same accuracy, and a precision optical sensor can now take up half the space while recording the same data channels.
