The Helium Sniffing Leak Test Method is commonly used on products or systems that may be too large to place inside a test chamber, or when location and repair of a discovered leak is important. In production environments helium sniffing is typically used to test for leaks in the range of 10-6 atmcc/sec and larger. This method is used to measure out-leakage of a part or system filled with helium as a tracer gas. A sniffer probe attached to a helium leak detector is scanned over the test part by an operator or a robot to identify suspect leak locations.  

Check out the products and customer project examples listed below that use the helium sniffing test method.
