Yes. The MSA ALTAIR 5X (part 10116926) is purpose-built for confined space entry because it ships as a complete pumped kit: the detector plus an internal sample pump, a 10-ft (3 m) sampling line and a 1-ft (305 mm) probe, so you can draw and test the atmosphere inside a tank, vessel or manhole before anyone enters. It detects LEL, O₂, CO and H₂S out of the box, monitors up to 6 gases simultaneously with interchangeable XCell sensors, is intrinsically safe (UL 913 / CAN/CSA C22.2), survives a 10-ft (3 m) drop, carries a minimum IP65 rating, and adds MotionAlert (man-down) and InstantAlert (manual panic) alarms.

The MSA ALTAIR 5X 10116926 detects four gases as standard — combustible gas (LEL), oxygen (O₂), carbon monoxide (CO) and hydrogen sulfide (H₂S) — and can monitor up to 6 gases simultaneously using interchangeable XCell sensors. It is approved to UL 913 and CAN/CSA C22.2 for intrinsic safety in hazardous (classified) locations, and it carries a minimum IP65 rating (third-party certified) for dust and water ingress.

The MSA ALTAIR 5X 10116926 uses MSA XCell sensors with these standard measuring ranges: combustible gas (LEL) 0–100% LEL (or 0–5% CH₄), oxygen (O₂) 0–30% by volume, carbon monoxide (CO) 0–1999 ppm, and hydrogen sulfide (H₂S) 0–200 ppm. Because the XCell slots are plug-and-play, the instrument can be reconfigured with other sensors (up to 6 gases) if your application changes.

XCell Sensor Technology is MSA's platform of interchangeable, plug-and-play sensors used in the ALTAIR 5X, each built with a proprietary embedded ASIC microchip that drives the sensor and outputs a digital signal. This design performs real-time environmental corrections and delivers an industry-first 60-second span calibration with sensor response and clear times under 15 seconds on LEL, O₂, CO and H₂S — about 50% faster than the industry average — while using roughly 40% less calibration gas per minute. XCell sensors are rated for up to 4 years of life, about 60% longer than the industry average.

MotionAlert and InstantAlert are two MSA-exclusive safety alarms built into the ALTAIR 5X. MotionAlert is a man-down feature that triggers automatically when the detector senses no movement for 30 seconds, signaling that the wearer may be immobile. InstantAlert is a manually activated panic alarm the user can trigger to warn others of a dangerous situation. Both are backed by visual, vibrating and audible alarms so coworkers are alerted when seconds matter.

Yes. The MSA ALTAIR 5X 10116926 includes Bluetooth as a standard feature, and pairing it with the free MSA ALTAIR Connect app (available on Google Play for compatible Android devices) turns a phone into a safety and productivity tool. Through the app you can view live gas-detection readings and man-down alerts, configure instruments remotely, automate gas-detector records and events, and send gas alarms via text — driving greater productivity and supervisory awareness of worker safety.

The 10' sample line and 1' probe let the ALTAIR 5X's internal pump actively pull air samples from a distance, so you can remotely test the atmosphere deep inside a confined space before entering — something a diffusion (passive) detector cannot do, since diffusion units only read the air immediately around them. On the 10116926 the internal pump has a recessed inlet that minimizes snag hazards and break points, making it a pumped monitor built for pre-entry sampling. The kit ships with the 10-ft (3 m) sample line, 1-ft (305 mm) probe, calibration cap and tubing.

The MSA ALTAIR 5X 10116926 is built for demanding field use: it has a thick, rubberized non-slip housing that survives a 10-ft (3 m) drop test and carries a minimum IP65 rating (third-party certified) against dust and water ingress. Large buttons can be operated with a gloved hand, and it supports visual, vibrating and audible alarms plus data logging for a full record of exposures.

The MSA ALTAIR 5X offers an industry-first 60-second span calibration and a 10-second bump test, with sensor response and clear times under 15 seconds on LEL, O₂, CO and H₂S — about 50% faster than the industry average — while using around 40% less calibration gas per minute (typical cost savings of more than 50% on calibration gas). Calibration and bump testing can be automated with the MSA GALAXY GX2 Automated Test System, and fleets can be managed through MSA Grid software.

The MSA ALTAIR 5X 10116926 ships as a monochrome-display Standard Kit configured for LEL, O₂, CO and H₂S, including the multigas detector with internal sample pump, a 10-ft (3 m) sample line, a 1-ft (305 mm) probe, a rechargeable battery pack, a 120V charger, a calibration cap with tubing, data logging, a CD manual and a Factory Calibration Certificate. It is sold by Industrial Safety Products with free shipping.

The MSA ALTAIR 5X 10116926 is covered by a full three-year manufacturer warranty on its LEL, O₂, H₂S and CO sensors, and MSA rates its XCell sensors for those gases at up to 4 years of expected sensor life — about 60% longer than the industry average. It also features an MSA-exclusive end-of-sensor-life warning that flags a sensor before it fails, helping reduce unplanned downtime and inventory replacement.

Both are MSA multigas detectors, but they target different needs. The ALTAIR 5X (10116926) is a proven, monochrome-display instrument that ships as a complete pumped kit — internal pump, 10' sample line and 1' probe — with XCell sensors, Bluetooth, a 60-second span calibration and GALAXY GX2 compatibility, making it a strong choice for standard confined-space and industrial gas detection. The newer ALTAIR io 6 is MSA's next-generation connected detector, built for real-time cloud monitoring and fleet efficiency. Choose the ALTAIR 5X for a dependable pumped detector; consider the ALTAIR io 6 if connected, real-time fleet monitoring is a priority. Both are available at Industrial Safety Products.
