Door-Safe - Model WT -Water-Tight Tester
The DOOR-SAFE is a fully ABS Type approved ultrasonic kit. It is used to rapidly and accurately test the integrity of watertight doors and hatches. The DOOR-SAFE WT tester kit consists of 2 units. An ultrasonic transmitter and a portable, handheld receiver unit connected to a flexible inspection microphone and hard hat compatible headphones. The transmitter and receiver are each supplied in protective leather cases fitted with neck-straps to allow for hands-free use.
The DOOR-SAFE™ kit is contained in a blue plastic foam-lined case for easy storage and transportation.
The DOOR-SAFE™ transmitter generates ultrasound on one side of the door or hatch, and the receiver unit on the other side of the door or hatch tires to detect any ultrasound.
If no ultrasound is detected the door or hatch is water-tight.
If ultrasound can pass through the doors or hatch seals, it means that so can water.;
If ultrasound is detected, it will be shown on the receiver unit in decibels, and also converted to an audible sound, which can be heard through the headphones.
The size of the problem can be established from the strength of the signal displaced in dB (decibels). This is the Classification Society DNV requirement.
