The MSA Altair 4 is our favorite choice for 4-gas detector rental. It's rugged, it's easy for your people to understand and use, and it's stable in the field under strange conditions. There's a reason they're the most popular detector in our rental fleet.
MSA's ALTAIR 4, Multigas Detector for LEL, CO, H2S, and O2 raises the standard for personal multigas detectors by offering a combination of features you won't find in competitive models.
The ALTAIR 4, Multigas Detector is the only portable gas detector with an optional MotionAlert™ feature if a user should become disabled due to unforeseen hazards. When enabled, the MotionAlert feature will activate an audible alarm if the instrument does not detect motion for 30 seconds, and is ideal for confined space entry applications. This unique gas detector function can be deactivated by the user. A high-contrast display and three large, rubberized buttons enable easy operation in low-light conditions.
The rubber over-molded housing is easy to grip, provides unsurpassed durability, is rated IP67 against dust and water ingress, and passes a 10+ foot drop test. This unit is equipped with a 95+ dB audible alarm and ultra-bright alarm LEDs on both its top and bottom for maximum visibility. Vibrating alarm and datalogging are standard features in this very competitively-priced unit.
MSA’s ALTAIR 4 Multigas Detector is Galaxy® System compatible for calibration and record keeping; a QuickCheck™ Test Station for fast, easy bump testing is also available. Data logging is a standard feature; the ALTAIR 4 Multigas Detector is MSA Link™ Software-ready.
