The ALTAIR® 4XR Multigas Detector Kit is a rugged 4-gas monitoring solution designed for comprehensive atmospheric testing and confined space safety. This configuration includes LEL, O₂, H₂S, and CO detection, along with a 4-gas calibration cylinder, regulator, and ALTAIR pump probe for remote sampling applications. Equipped with rapid-response MSA XCell® sensors, it delivers fast, reliable detection performance in demanding industrial environments and is backed by a 4-year instrument and sensor warranty.

Key Features

Complete monitoring kit: Includes 4-gas detector, calibration cylinder, regulator, and pump probe for remote sampling
Fast XCell® sensor response: Detects gases up to twice as fast as industry average
Extreme drop resistance: Survives 25 drops from 4 ft and incidental 25 ft drop onto concrete
Wide operating temperature range: -40°F to +140°F (-40°C to +60°C)
Bump LED compliance indicator: Quick visual confirmation of successful bump test
Efficient calibration process: Uses half the test gas and half the time compared to industry average

Time-of-day bump and calibration: Compatible with MSA GALAXY® GX2 Automated Test System
MotionAlert feature: Alerts others if the user becomes immobile
InstantAlert manual alarm: User-activated alarm for emergency situations
Bluetooth removed: Bluetooth functionality no longer available as of July 2022

Intended Use

The ALTAIR® 4XR Multigas Detector Kit is intended for atmospheric monitoring in hazardous environments where combustible gases, oxygen deficiency or enrichment, and toxic gases may be present. The included pump probe allows pre-entry testing and remote sampling.
