MSA ALTAIR io 4
Connected Gas
Detection Wearable

Out of the box and into the cloud. Cellular connectivity, GPS location awareness, and automatic bump and calibration through the ALTAIR io DOCK — with every device, event, and test record streamed to MSA Grid from day one.

Connected Safety

Built for turnarounds, plant maintenance, emergency response, and confined space entry

The MSA ALTAIR io™ 4 is a connected multigas detection wearable designed with fully integrated cellular connectivity, so your worksite has real-time visibility from day one. It monitors LEL, O₂, CO, and H₂S using MSA XCell® sensor technology, streams device data straight to your MSA Grid account, and updates over the air — no docking station required for firmware or configuration changes. At Jendco Safety Supply, the io 4 is backed by a complete ecosystem including the ALTAIR io DOCK, gas cylinder holder, and 5-device smart charger to simplify calibration, compliance, and fleet management.

4 LEL, O₂, CO, and H₂S monitored on one connected wearable.
IP68 Dust and waterproof rating — 2 m for 1 hour.
25 ft Capable of surviving an incidental 25 ft (7.5 m) drop onto concrete.
17 hr Typical battery life on LTE-M from a 2 Ah rechargeable pack.

Detect. Dock. Charge. Calibrate. Track.

A gas detection program that runs itself — less manual paperwork, better compliance visibility.

The ALTAIR io 4 ecosystem pairs the connected detector with the ALTAIR io DOCK automated test stand, a gas cylinder holder for organized calibration gas management, and a wall-mountable 5-bay smart charger. Together they standardize bump testing and calibration, mark devices as digitally returned the moment they hit the charger, and keep a deployment-ready fleet across crews, shifts, and job sites.

MSA ALTAIR io 4 Multigas Detection Wearable

Designed with fully integrated connectivity for real-time visibility across your worksites from day one

The MSA ALTAIR io 4 is a connected gas detection wearable built for industrial worksites, turnarounds, and emergency response — combining LTE-M cellular connectivity, concurrent GNSS location awareness, and MSA's patented XCell® sensor technology in a package rated to survive the job.

  • Automatic connectivity. Device data streams instantly and securely to the cloud, available anytime on MSA Grid.
  • Over-the-air updates. One-click configuration and firmware changes pushed to the whole fleet.
  • Automatic bump and calibration. Place the device on the ALTAIR io DOCK and the correct test starts on its own.
  • MSA id™ digital device assignment. Built-in RFID reader ties every device to the right worker.
  • Workproof durability. IP68, 26 drops from 4 ft (MIL-STD-810G), and survives an incidental 25 ft drop onto concrete.
  • Always under warranty while covered by an active MSA+ subscription.
