The T40 Rattler™ is a low-cost, maintenance-free single gas monitor designed to protect personnel from
dangerous hydrogen sulfide or carbon monoxide gas exposure in the most extreme conditions. Despite its
compact size, the T40 Rattler™ includes features usually found only in larger multi-gas monitors – including a
large, liquid crystal display (LCD), internal vibrating alarm, audible/visual alarms and simple push-button operation.
