Different manufacturers’ gas detector components are not identical and provide different results. Interchanging raises costs and may needlessly delay the end user’s work, says Bryan Truex.
Claiming that one manufacturer’s detector tube and pump system parts and components are interchangeable with the parts or components of another manufacturer’s system implies sufficient standardization of the parts and components has taken place to permit substitution with no loss of function or suitability. The claim implies the interchangeable part or component is a virtual duplicate of the part it replaces and that it provides identical performance. However, no such standardization exists.
There are no industry-recognized standard performance specifications for detector tube and pump system parts and components. The parts and components of different manufacturers’ detector tubes and pump systems function differently, have different specifications, have different physical dimensions, meet different quality standards, and are not identical.
