The MSA Altair 4xR MultiGas Detector is a rapid-response, four-gas monitor. This model has been configured to include methane (CH4 LEL), oxygen (O2), hydrogen sulphide (H2S) and carbon monoxide (CO) sensors, a charcoal case and a charging cradle. It is suitable for use in the following sectors: fire service, construction, industrial, mining, oil and gas, and utilities. For an overview of the MSA Altair 4xR MultiGas Detectors, please see the following video.
To enable gas detection that is two times faster than the industry average, the MSA Altair 4xR MultiGas Detector is equipped with MSA XCell® Sensors. As a result, it can provide live gas readings; this version of the MSA Altair 4xR MultiGas Detector includes XCell® sensors for methane, oxygen, hydrogen sulphide and carbon monoxide, equipping it with the following measurement ranges.
Gas | Range | Resolution |
Methane (LEL) | 0–100 % | 1 % |
Oxygen | 0–30 % | 0.1 % |
Hydrogen Sulphide | 0–200 ppm | 1 ppm |
Carbon Monoxide | 0–1999 ppm | 1 ppm |
When the MSA Altair 4xR MultiGas Detector measures hazardous gas concentrations it will alert the user by issuing acoustic, visual and vibrating alarms.
The MSA Altair 4xR MultiGas Detector also features a low battery alarm; when the battery is close to expiration the MSA Altair 4xR MultiGas Detector’s on-screen battery indicator and LEDs will flash, an alarm will sound, and LOW BATT will be displayed on the screen.
Rapid-responding MSA XCell® sensors also mean the MSA Altair 4xR MultiGas Detector can provide teams with real-time incident awareness when wirelessly connected to the MSA Altair Connect App (available via Google Play) via Bluetooth. To facilitate faster Bluetooth connection the MSA Altair 4xR MultiGas Detector includes an RFID chip.
When connected to the MSA Altair Connect App, event notifications will be sent to relevant persons via text message. The MSA Altair 4xR MultiGas Detector includes a MotionAlert option that informs colleagues when a member of their team has become inactive. Similarly, the user-activated InstantAlert notifies other team members of potentially dangerous situations. The MSA Altair Connect App also allows the user to create notification groups, email calibration details, and receive compliance reminders, as well as update the MSA Altair 4xR MultiGas Detector’s settings quickly.
To ensure correct functionality, the MSA Altair 4xR MultiGas Detector will perform a complete self-test upon initial start-up. The self-test ensures that acoustic and vibration alarms, as well as LED signals, are working correctly.
In addition to this, the MSA Altair 4xR MultiGas Detector can be used with MSA Galaxy GX2 Automated Test System (NOT included) to perform Bump tests and calibrations in half the time with half the test gas compared to the industry average. Successful Bump tests are indicated by an on-screen tick and Bump LEDs.
Finally, to ensure suitability for rugged outdoor environments the MSA Altair 4xR MultiGas Detector features an IP68-rated design: it will remain functional even after submersion in 2m of water for up to one hour. Furthermore, the MSA Altair 4xR MultiGas Detector is constructed to survive up to twenty-five drops from 4 feet (1.2m) or an incidental drop from 25 feet onto concrete. It has an operating temperature of -40°C to +60°C.
The MSA Altair 4xR MultiGas Detector is a durable, dependable and fast-responding four-gas monitor.
