Ultrasonic Hatch Cover Tester

Did you know sea water ingress is one of the significant sources of damage to cargo? This can result in costly insurance claims, which can be avoided if you’re using the right equipment. At Cygnus Instruments, we designed the ultrasonic hatch leak detector to test for potential water leaks and the weather tightness of cargo hatch covers and doors.Consisting of a battery powered transmitter comprised of 19 ultrasound emitters (40 kHz), our Cygnus Hatch Sure emitters are arranged to produce an omnidirectional sound field. This is then uniformly distributed throughout the cargo hold. The sound energy level is then displayed by the receiver part of the system, which identifies the location of leaks promptly and accurately.With a three year warranty, this powerful and robust transmitter has a variety of benefits. As well as being easily transportable in its rucksack style case, our Ultrasonic Hatch Cover Tester can be used in place of hose testing, making it an environmentally friendly alternative.
