Especially when checking for, leakage rates in installing special hazard fire suppression systems, the Portascanner 520® room integrity tester allows users to locate the exact location and severity of leak sites. When checking leakage rates using door fan testing for example, it is incredibly hard and time consuming to locate leaks. Using the naked eye, it is almost impossible to do accurately. The Portascanner 520® in a matter of seconds can locate all major leak sites, allowing prior repairs to be carried out and thus ensuring Pressure tests will pass first time. It is the time saving before carrying out door fan testing where ultrasonic room integrity tester technology can be invaluable.

Three Core Benefits

1. World-Class Accuracy

The most accurate unit of its type locating a leak site via visual and audible readings and identifying its extent with a definitive numerical result. Can test leaks as small as 0.06mm. Compared to the rival puffer test technology which is a purely visual inspection. Ideal for room integrity testing and especially cable trays, windown or door structures and all common defect areas.

2. Quick & Easy to use

It is a simple system, that is both easy to learn and operate. Testing can be completed quickly by one person and can also be done without disrupting the building occupants, unlike smoke puffer tests which involve evacuating a building or room.

3. Non Destructive & Clean

The Portascanner 520 is a completely clean and damage free technology, which can be used in the sensitive environments clean agent systems operate in.

Room integrity testing – Complying with Regulations for Clean Agent Fire Suppression Systems

CURRENT SITUATION:Before installing Clean Agent fire suppression 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 to calculate the overall leakage of a room.

LIMITATIONS:Locating exact leak sites is currently done by a “puffer test” with smoke. However, such current methods do not provide precise, accurate results on leak location or size.

SOLUTION:Today, the industry can benefit from using the Portascanner™ Integrity Test Indicator alongside the Door Fan Testing for a complete and comprehensive regulatory room test. Ideal for precise leak detection, Portascanner™ is an exceptionally accurate (to 0.06mm) and fast method. It is the first of its kind, intuitive to use, non-invasive, and consequently, is of immediate use to the Fire Industry.


Also available in Watertight version, ideal for identifying the leak sites in Watertight seals, as opposed to airtight seals. Known as the Portascanner Watertight 


1. Receiver Rod - The user directs the rod at areas they wish to survey. Any escaping ultrasound if received by the rod and sent to the main unit.

2. Headphones - Any ultrasound that is identified by the unit is outputted as audible readings via external headphones.

3. Receiver - The receiver processes and displays any ultrasound that emitted from a leaking space. The results are visually presented to the user on the user on an internal screen as well as outputted to external headphones.

4. Generator - The generator is an ultrasonic generator with three transducers. The transducers emit a strong signal in one direction that fills the room/space with pulses of ultrasound
