Where ever there is the need to stop water ingress there is a good chance that ultrasonic can help.
Often called ‘UT’ or ‘UT testing’ it consist of generating ultrasonic sound using an ultrasonic transmitter, placing this physically on one side of whatever you are testing and then checking on the other side with a receiver tuned to the transmitter frequency to see if there is any ultrasound detected. ultrasound can only be heard an air hole.
Ultrasound is not audible so the receiver converts the ultrasound to an audible sound.
This audible sound is heard through headphones or a small internal loudspeaker. If it is desirable to know the size of the hole, then we have products that will display the intensity in decibels. Decibels are the universal unit for sound measurement.
The product we make to test for leaks in hatch covers and atriums where there is a large volume that needs testing we suggest our Cargo-Safe.
