DETECT 1000 leak detector is designed to enable professionals to carry out all types of test.

It is formulated to ensure ideal operation with high sensitivity, and also for macro-leaks requiring high surface tension.

Usable on all gases except pure oxygen at high pressure (> 150 bar).

All fluids (liquids and gases), even if they are not pressurised, naturally seek to escape from a container, especially if it has even the slightest of discontinuities. The result is a leak.

The integrity of a container is thus its ability to resist the flow of the fluid enclosed within it. In practice this function is more easily defined by its converse, namely the permeability of the container, i.e. the extent to which it allows its contents to escape or leak. It is easy and convenient to distinguish between two types of integrity for a container, depending on the surface continuity with the fluid:

Volumetric integrity, relating to the continuous surfaces of the container.

Integrity of an assembly or link, i.e. at the join between two continuous surfaces, broken down into static integrity and dynamic integrity during translation or rotation.

Note that it is impossible to obtain theoretically perfect integrity (especially with gases), due to the molecular nature of fluids.

"Absolute integrity" is an unrealistic statement that should be avoided. This does not exclude very high integrity levels, though; these may be defined in three classes: strict, relative, controlled.

It is, however, important to realise that a leak generally contains a random component, and that it often evolves over time. The leak will not be the same at the start of the mechanism’s life cycle as at the end. Accordingly, it is always useful to specify the maximum acceptable limits and to carry out continuous checks.

This detection aerosol can be used to measure all gas leaks, and is categorised as a general method not requiring special equipment.

It makes use of the spray and bubble method. The cost of a test is low compared to the investment. The method is highly reliable and offers excellent sensitivity; it can be used on any site.

Note that in extreme cases, if the pressure inside the bubble is close to atmospheric pressure, the bubble may only start to form once the pressure from the leak is sufficient to overcome the surface tension.
