Designed to protect personnel from dangerous hydrogen sulfide or carbon monoxide gas exposure in the most extreme conditions. This unit is ideally suited for applications in such diverse climates as the desert or the arctic.

T40 Rattler is compact and lightweight. It can be easily be clipped to a belt, shirt pocket or hard hat. Gas concentrations are clearly read on a four-digit, seven segment liquid crystal display (LCD). And it will alert the user with either audible, visual or vibrating alarms when a preset high, low  value is exceeded.

The peak-hold feature captures the highest reading from initial turn-on. Easy calibration uses a unique flip-cap, one button routine. Operates for approximately 500 hours on a single AA alkaline battery. The T40 Rattler carries a two-year warranty from date of manufacture.

Monitor is supplied with battery installed, belt clip and an instruction manual. If you desire a suspender attachment in lieu of the standard belt clip, please advise in the "special instructions box" at check out. We can make this substitution at no additional charge.
