The SDT MacGregor-Navire Ultrasonic Hatch Leak Detector is a specialized marine inspection and testing system designed for checking the watertight and airtight integrity of hatch covers, watertight doors, bulkheads, and ship compartments. It is widely used by ship owners, surveyors, marine engineers, and classification societies for routine inspections and pre-cargo safety checks.
This system works on ultrasonic sound transmission, where an ultrasonic signal is generated inside the cargo hold or compartment. Any leakage through hatch covers, seals, gaskets, or joints allows the ultrasonic signal to escape, which is then detected externally using a handheld ultrasonic receiver. This method provides accurate, non-destructive, and fast leak detection without the need for water hose testing or chalk testing.
The SDT MacGregor-Navire kit is supplied as a complete portable system, including the ultrasonic detector unit, transmitter, probes, sensors, headphones, cables, accessories, and a rugged protective carrying case. It is ideal for use during vessel surveys, dry dock inspections, and routine onboard maintenance.
