TracerMate II works with helium, the most common tracer gas used for micro-leak detection, but it can also control systems with other gases such as Forming Gas, a hydrogen/nitrogen mix, or carbon dioxide. Manufacturers can use TracerMate II to perform a high-resolution pressure decay test followed by leak location on the same test station.

A Language of Its OwnDetector Selection PlacementArchitectural AspectsAs do most scientific and engineering pursuits, the detection and measurement of toxic and hazardous air contaminants has its own language and acronyms. Key definitions among these are: 1. Time weighted average (TWA) is an average gas concentration over time 2. Permissible exposure limit (PEL) is an eight-hour TWA 3. Short-term exposure limit (STEL) is an acceptable average exposure over a short period of time, usually 15 minutes 4. Ceiling value (C) is the exposure limit that shall at no time be exceeded.
