DOOR-SAFE™ Water-Tight Tester                                                                

Door-Safe

Overview of the DOOR-SAFE™

ABSThe fully ABS Type Approved Door-Safe™ ultrasonic kit is used to rapidly and accurately test the integrity of water-tight doors and hatches.

The Door-Safe™ WT tester kit consists of 2 units, an ultrasonic transmitter unit and a portable, hand-held 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 complete Door-Safe™ kit is contained in a blue plastic foam-lined carry case for easy transportation and storage.

If ultrasound can pass through the door or hatch seals, then it is also true that water may be able to pass through.  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 tries to detect any ultrasound.  If none can be detected the door is water-tight.  Any ultrasound that has leaked through is shown on the receiver unit in decibels on the digital LCD display and also converted to an audible sound, which can be heard through the headphones.  The size of the problem can also be established from the strength of the signal displayed in the universal requirement of decibels.

How to Operate the DOOR-SAFE™ Water-Tight Tester

1. Plug in the headphones and inspection microphone to the receiver unit.

2. Turn on the transmitter unit and place on one side of the door or hatch.

3. Obtain an open door value as a reference.

4. Close and seal the door and from the other side, pass the inspection microphone over the door seals to see if any of the ultrasound emitted from the transmitter unit can be detected.

5. To be water-tight the value must be 0 dB, if a value of 1-10% of the open door reference value is detected the seal is accepted as weather-tight, any readings above 10% of the open door value and the door is not weather or water tight.
