Msa Safety 10153986 Co Gas Detector 25 Ppm 100 Ppm

Product Description

The MSA SAFETY 10153986 is the ALTAIR 2X single-gas carbon monoxide detector, built for continuous personal gas monitoring in industrial and commercial environments. It runs on MSA Xcell Sensor technology, which integrates controlling electronics directly inside the sensor using a proprietary application-specific integrated circuit (ASIC) design. The result is faster response times, greater accuracy, and a rated sensor life exceeding four years. The low alarm triggers at 25 ppm CO and the high alarm at 100 ppm CO. Licensed safety professionals and industrial hygienists rely on this unit for confined space entry, utilities work, and any task site where CO buildup is a known hazard.

The ALTAIR 2X is suited for residential and commercial service calls as well as heavy industrial applications including oil and gas, wastewater, mining, and construction. It is commonly worn as a personal protective device by HVAC technicians, plumbers, utility workers, and confined space entry teams. The unit is compatible with the MSA GALAXY GX2 Automated Test System and MSA Link Pro software, enabling automated bump testing, calibration, and data logging for teams managing fleet compliance across multiple instruments.

Compatibility

Compatible with the MSA GALAXY GX2 Automated Test System and MSA Link Pro software for automated bump testing, calibration scheduling, and compliance data management.

Installation Notes

The ALTAIR 2X is a personal worn gas detector and does not require fixed installation. Clip the unit to a shirt collar, lapel, or chest harness in the breathing zone per OSHA and site safety protocols before entering any potentially CO-affected area. Perform a bump test before each day of use to confirm sensor response and alarm functionality. Calibration and bump testing should follow the manufacturer schedule and any applicable OSHA 29 CFR 1910.146 confined space entry requirements.
