Current Situation:
Before installing clean agent fire suppressing systems the integrity of the building structure commonly undergoes “Door Fan Testing:. This test determines the Peak Pressure and Agent hold time necessary for ensuring the effectiveness of these fire suppression systems. As required by NFPA 2001 and ISO 14520 standards, it is best to calculate the overall leakage of any room.

Locating exact leak sites as an ultrasonic leak detector is currently done by a “puffer test” with smoke. However, such current methods do no provide precise, accurate results on leak location or size.


Today, the industry can benefit from using the Portascanner Integrity Test Indicator along the door fan testing for a complete and comprehensive regulatory room test. Ideal for precise leak detection, Portascanner 520 is an exceptionally accurate up to 0.06mm and fast method to find leaks.

Coltraco Ultrasonics Limited is regarded to be a world popular ultrasonic manufacturer and supplier, which produce a huge variety of products to assist industrial sectors with monitoring and measuring requirements. They are working within this field for more than 20 years for which they have experience with more diversity. The Portascanner Watertight is one of its products, which is also known as watertight integrity testing device. It has two main components – a generator and receiver. The ultrasound generator emits a specific frequency of ultrasound (40,000 Hz). It is magnetic so can be attached onto a wide range of surfaces within sealed areas. The receiver then picks up the signal and converts it into a result indicating W/T integrity.


    The receiver is tuned to detect a specific frequency of ultrasound.
    The receiver comes with a sensor rod, which allows a user to scan the entirety of a seal at close range.
    The receiver has both a visual and audio output which gives off better results for Hatch cover maintenance and watertight integrity testing.
    The visual output is shown on the LCD screen of the receiving unit. It is read mathematically and in decibels.
    There is a numerical representation, which can be changed into a decibel (dB) reading, allowing seals to be tested to certification society standards.
    There is also a bar graph representation of the strength of the ultrasonic signal, which is being detected.
    The audio signal is delivered via headphones, which plug into the receiver unit (standard 3.5 mm jack).
    The receiver uses a process called heterodyning to change the ultrasound signal received into an audio signal, which the user can hear.


    The generator is placed on one side of a sealed compartment and turned on.
    The user stands on the other side of the compartment and uses the sensor rod to scan the seal.
    The receiver displays the strength of detected signal on the screen and the user can also hear it through the headphones.
    Leak sites will be apparent from increased signal strength
    This will be shown by an increase in the readings on the screen display and in the volume of the audio signal
