MSA ALTAIR (10092522)
MSA Altair Single-Gas Detector, (CO) (Low: 25ppm, High: 100ppm), UL
In Stock
A carbon monoxide (CO) detector, not a CO2 monitor, with alarms at 25 ppm and 100 ppm. It is sealed to IP67, runs maintenance-free for two years on its built-in battery, and alerts by flashing LEDs, sound and vibration while logging the last 25 events. UL and CSA listed for hazardous locations, it suits buyers who want rugged CO protection rather than ventilation monitoring.
