The unit is designed to notify users of gas monitoring with visual alarms of ultra-bright LED lights (which remain visibly noticeable when stored in pockets) and a screen display, distinct audible alarms of over 95 decibels, and vibrating alarms. The triple alarm system will ensure that users and those nearby are appropriately alerted to gas situations in the environment. Most notably, the alarm system is designed to alert users regardless of hearing or visual impairment.

The Alarm can be worn as an attachment to a Lab Coat, or hung in the lab from a hook.  See photos. 

Altair Maintenance-Free Single-Gas Detector features

The unit also features patented MSA-built Button Cell toxic gas sensors. The breakthrough design utilizes stainless steel construction and its technology virtually eliminates sensor leakage. The oxygen sensors are equipped with industry standard fast response sensors. Furthermore, its use of microelectronic technology ensures that the cell size does not interfere with the portability of the device.

Worksites interested in assessing alarm conditions and history will find the automatic internal record keeping of the device to be useful. Using MSA InfraRed communication technology, the Altair Maintenance-Free Single-Gas Detector automatically stores the last 25 alarm events. The InfraRed communication adapter allows users to adjust settings and assess alarm conditions.

The Altair Maintenance-Free Single-Gas Detector offers a display that is easy to read. Alerts are noted in a large numeric display, and many functions may be performed with the touch of a button. The oxygen version allows users to monitor current levels as well as highest and lowest readings with ease.

The unit’s ease of use is integral when working in potentially dangerous conditions. These low maintenance unit’s are key features of the products advanced design. Long-life lithium batteries typically perform for two years or more, and are designed to outlast a two-minute alarm mode per day. This type of battery efficiency places the Altair Maintenance-Free Single-Gas Detector well above its closest competitors in longevity.

The unit allows for easy bump checks by pressing “Gas Test.” Once tested, the unit displays a checkmark on the screen for 24 hours. The detectors also offer built-in calibrations, as required for some worksites. For other gas response tests and bump checks, the Altair Maintenance-Free Single-Gas Detector is compatible with Altair Quick-Check Stations. These stations are another maintenance free way to ensure the quality and reliability of the industry’s leading gas detection devices.


Not only is the unit functional, but it is built to last. With a suspension clip allowing versatility in placement, the unit is designed to be worn where needed and remain in place even during the roughest use. The gas detector is also housed in an ultra-thick rubberized casing which can withstand accidental drops. The Single-Use Gas Detector is also water and dust resistant and provides a seal tight enough to exceed industry averages. Weighing approximately 4 ounces, the Altair Maintenance-Free Single-Gas Detector is highly portable and may be worn anywhere on the body near the breathing area.
