MSA Altair 4X Multigas Detector | Refurbished Unit | 24-Hour Runtime & XCell Sensors
The MSA Altair 4X (GDU) is an exceptionally durable multigas detector engineered to provide reliable gas detection in the most demanding environments. This refurbished unit utilizes XCell sensor options to measure up to four gases simultaneously, including combustible gases, O2, CO, H2S, SO2, and NO2. With a digital sensor output, the device is significantly less susceptible to RF interference, ensuring stable readings in industrial settings.
How long does the MSA Altair 4X battery last?
The unit provides an industry-leading 24-hour run time, which exceeds standard industry averages by approximately 71%. This extended battery life is complemented by XCell sensors designed for a four-year life cycle, lasting 60% longer than typical sensors.
Is the MSA Altair 4X built for extreme industrial use?
Yes, this detector features a ruggedized housing designed to withstand a 20 ft (6m) drop. It is also highly efficient, using less than half the calibration gas required by standard competitive models, reducing long-term maintenance costs.
What integrated safety alarms are included?
The device includes the exclusive MotionAlert system, which activates if the user becomes immobile, and InstantAlert, a manual alarm allowing users to immediately notify others of hazardous conditions. These features make it essential for firefighting, welding, and confined space operations.
