Acoustic Correlation vs Tracer Gas: Which Finds Harder Leaks?

When acoustic wins and when you need tracer gas — the two most sensitive methods compared.

Acoustic correlation and tracer gas are both highly sensitive, but they work differently. Here's when to use each.

Factor	Leak.ca	Tracer Gas Detection
Best for	Pressurized pipe leaks, long pipe runs, water mains	Acoustic: high pressure. Tracer gas: low pressure/complex
Minimum detectable leak	Depends on pressure and pipe material	Tracer gas detects microscopic leaks (1 PPM)
System must be	Under pressure (acoustic needs water escaping)	Depressurized and filled with tracer gas
Access required	Two points on same pipe for sensors	One injection point + surface access for detector
Best for	Underground mains, long service lines, pressurized systems	Complex piping, low-pressure systems, sensitive buildings
