A tracer-gas leak testing method is a nondestructive testing method that detects gas leaks. A variety of methods with different sensitivities exist. Tracer-gas leak testing is used in the petrochemical industry, the automotive industry, the construction industry [1] and in the manufacture of semiconductors, among other uses.

Understand the essential properties of a tracer gas and the benefits of using helium with leak detectors for vacuum systems

Tracer gas leaking is used to detect extremely low leak rates. See our resources on sniffing, hard vacuum, clamshells, accumulation, and other helium test solutions.

At Pfeiffer Vacuum we specialize on leak detection with tracer gases due to the unrivalled sensitivity and selectivity of tracer gas methods compared to other leak detection procedures. Tracer gas methods are insensitive to temperature changes, elastic behavior of test specimens and provide the fastest test cycle times in a production environment.

Tracer gas testers are highly sensitive and can detect leaks as small as 10⁻⁸ SCC/sec. Helium or Hydrogen gas has a low molecular weight and can easily escape through tiny leaks, making it easily detectable. Tracer gas testing can also help in determining the leak location by moving the sniffer over your test part.

2024年5月3日 · Tracer gas leak detection, sometimes called tracer gas leak testing, is a method used to identify and locate leaks in underground pipes. It involves introducing (with pressure) a harmless, detectable gas (such as helium or hydrogen) into the pipe system.

Tracer gas leak testing is a simple and efficient method for detecting leaks during manufacturing in pipe joints, tubes and fittings, coils and compressors. This guide includes: The basics of tracer gas leak testing and how it works; The five different tracer gas leak test methods for HVAC/R components; The pros and cons of each method

2025年2月4日 · Tracer gas detection is an alternate method for pinpointing pipe leaks when sonic detection isn’t possible or when a secondary method to confirm location is required. The process starts by sealing off a suspect pipe with pressure testing …
