Spray Test

This method is used for leak localisation of parts under vacuum.

The leak detector will evacuate the air inside the tested product. Tracer gas is then sprayed over the outer surface. The detector measures the flow of gas penetrating the product and the leak can be located.

Main advantages

• Ability to locate the leak
• Very high sensitivity
• Easy to perform
• Local or global test
• Detector cost only, no tooling
