Ultrasonic leak detector for room integrity testing


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

Frequently asked questions

What materials can the Portagauge 5 test?

The portable ultrasonic thickness gauge can test any type of metal and most hard plastics. The most popular metals include steel, aluminium, copper and popular plastics include PVC, Polyethene and fibreglass to name a few!

How accurate is the Portagauge 5?

The Portauage 5 is accurate at testing true material readings (ignoring surface coatings) to within 0.01mm

How to test sprinkler pipes?

The Portaguage 5 can be used to test any sprinkler pipe or other metal piping to identify areas of corrosion, locations where there has been considerable erosion, areas of fungal deterioration and other forms of metal ware. The testing process involves carrying out a series of spot checks along the bottom of the pipe. It is on the bottom of the pipe where liquid will naturally pool and thus where you are much more likely to have areas of heavy corrosion. The user simply goes down the entire length of the sprinkler pipe and continually monitors the pipe thickness and the waveform. Both should be consistent along the full length of the pipe. As soon as the thickness or the waveform begin to deviate significantly, (and they will normally do so together) the equipment has identified an area likely to be compromised and thus further physical & visual inspections will be required.

Do I need training to use the Portagauge 5?

This equipment is incredibly easy to operate, and no dedicated training is required in order to use the unit. We provide operating instructions which is normally enough to provide an operator with confidence and the required knowledge. However, every Coltraco unit comes with free technical support for the lifetime of the equipment so if you do need any further assistance, our technical team are on hand to support

How long does it take to deliver the portable thickness gauge?

These units are almost always available ex stock from the UK. Delivery to the UK is normally next day, Europe in 2 – 3 days and most of the rest of the world in 3 – 4 days from order. Please contact our sales team for an update on availability and for any other questions.

I don’t need to ignore the paint layer. Will this still work for my needs?

The short answer is yes and normally triple echo thickness gauge technology can be used for any thickness measuring applications. We do also offer our Portagauge 3 technology however which uses single echo technology and will measure paint & material as one reading.
