About Sniffing
Sniffing is a good leak detection method which is used to locate leaks in pressurized systems by “sniffing” for tracer gases, typically helium, escaping from a component. In this method, the part is filled with helium, and a sniffer probe connected to a leak detector is passed around joints, seals, and welds. If helium escapes, the detector identifies its presence, indicating the exact leak location. Sniffing is a non-destructive, highly sensitive technique suitable for industries like automotive, aerospace, and HVAC. It ensures accurate leak detection without damaging the product, making it essential for quality control and safety assurance.
About Helium Leak Testing
Helium leak testing is a highly accurate and sensitive method. It is used to detect and locate leaks in sealed or pressurized systems. This technique involves using helium gas as a tracer due to its small atomic size, inert nature, and low presence in the atmosphere. Components are either pressurized with helium or placed in a helium-rich environment, and any escaping gas is detected using specialized leak detectors. Helium leak testing is widely used in industries like automotive, aerospace, medical devices, and refrigeration, where safety and reliability are critical. It offers fast, non-destructive, and precise results, ensuring product integrity and quality.
Typical Helium Sniffing Leak Test Procedure
The helium sniffing procedure is a highly sensitive, non-destructive leak detection technique It is used to locate leaks in sealed or pressurized systems. It involves introducing helium gas—an inert, non-toxic, and easily detectable gas—into the component under test.
Helium is best for this process because of its small atomic size, which allows it to escape through the tiniest openings, and its low natural concentration in the atmosphere, which minimizes background interference. When the sniffer detects helium, it sends a signal indicating the presence and location of the leak.
This procedure is commonly used in such industries like automotive, aerospace, HVAC, refrigeration, and medical equipment manufacturing—especially where precision and safety are critical. The helium sniffing method allows operators to pinpoint the exact location of a leak without damaging the component.
Why is Helium important for sniffing?
Helium is vital for leak detection. One of the main reasons helium is preferred for sniffing is its small atomic size. It can pass through extremely small leaks that other gases cannot, allowing for the detection of even the tiniest imperfections in seals, welds, or joints. Additionally, helium has low natural abundance in the atmosphere (around 5 ppm), which reduces the chances of background interference and ensures high detection sensitivity.
Helium is also easily detectable using highly sensitive leak detectors, which can identify leaks as small as 10⁻⁶ mbar·l/s. This makes helium sniffing an incredibly accurate and reliable method for pinpointing leak locations.
We utilize the advantages of helium to deliver top-quality leak detection systems that ensure product integrity, safety, and compliance with industry standards.
