What Matters for This Task
Noise makes an audible alarm only one part of a monitoring arrangement. A vibrating personal instrument must also be worn as instructed and checked before use. ALTAIR 4XR is the relevant multigas monitor here. Testo 316-EX remains a separate leak-location option and is not presented as matching the vibration feature.
