The MSA ALTAIR 4X Mining is an extremely durable multigas detector optimized for the mining industry. The ALTAIR 4X Mining simultaneously measures up to four gases while providing an additional layer of safety with MSA's MotionAlert™ and InstantAlert™ features. It is the ideal gas detector for the rugged and unforgiving environments found in all mining applications.

The MSA ALTAIR 4X Mining is compatible with a wide range of XCell sensor options including methane, O₂, CO, H₂S, and NO₂. XCell sensors surpass industry standards in several crucial areas. Their four-year sensor life is double the industry average, and they are engineered using MSA's proprietary application-specific integrated circuit (ASIC) design. By miniaturizing sensor controlling electronics and placing them inside the sensor itself, MSA XCell Sensors offer superior stability, accuracy and repeatability.

MSA XCell Sensors are a breakthrough in chemical and mechanical sensor design, enabling faster response and span calibration times. With less time spent on calibration and bump tests, you save calibration gas, maintenance costs and in turn, save money. But most importantly, in your industry, saving seconds on response time can also mean saving lives.

The ALTAIR 4X Mining Multigas Detector includes exclusive features like MotionAlert™ and InstantAlert™ providing additional layers of safety. The MotionAlert sensor activates when a user becomes disabled and motionless, quickly alerting others to the disabled user's location. And with a simple push of a button, the InstantAlert feature enables users to manually alert others to potentially hazardous situations.

The ALTAIR 4X Mining Multigas Detector is as tough and functional as it looks. A rugged housing provides unsurpassed durability, including the ability to survive a 20-foot drop. And with large, glove-friendly buttons and a high-contrast display, the ALTAIR 4X Multigas Detector is easy to operate in any work environment, even low-light conditions.

The MSA ALTAIR 4X Mining is available with a wide range of options. Please contact us for additional information.
