MSA Altair 4XR Gas Detector - with Bluetooth (Detector Only)


Complete 4-gas monitor with Bluetooth.

This version detects LEL, O2, CO, H2S.

Has Bluetooth so you can watch detector results, remotely in real-time on your phone!

Use it to lower a detector into a confined space to get a reading BEFORE you enter;
or to keep an eye on your colleagues' detector while you remain in a safe place.

Outfitted with rapid-response MSA XCell® sensors, the ALTAIR 4XR Gas Detector is the toughest 4-gas monitor on the market and is backed by a 4-year warranty. The ALTAIR 4XR can also provide real-time incident awareness to team members, supervisors, safety managers and others when paired with the MSA ALTAIR Connect app via a Bluetooth® wireless connection.

This is the device-only (without calibration kit).
Can self-calibrate & self-test if you have the kit... as long you have at least one detector with calibration kit then you can use the same kit on all your 4X and 4XR detectors! 

(Just be sure to use the correct gas for each detector, if you have different types of detectors).
