Yes. The MSA ALTAIR 5X Industrial Kit (part 10116927) is well suited to confined space entry because it detects five gases as standard — combustible gas (LEL), oxygen (O₂), carbon monoxide (CO), hydrogen sulfide (H₂S) and sulfur dioxide (SO₂) — and ships with an internal integral pump plus a 10-ft (3 m) sampling line and a 1-ft (305 mm) probe, so you can draw and test air from inside a tank, vessel or manhole before anyone enters. It can monitor up to 6 gases simultaneously with interchangeable XCell sensors and adds MotionAlert (man-down) and InstantAlert (manual panic) alarms for worker safety.

The MSA ALTAIR 5X 10116927 detects five gases as standard — combustible gas (LEL), oxygen (O₂), carbon monoxide (CO), hydrogen sulfide (H₂S) and sulfur dioxide (SO₂) — and can monitor up to 6 gases simultaneously using interchangeable XCell sensors, with additional options for CO₂, NH₃, Cl₂, NO₂ and VOCs. MSA states the detector meets or exceeds IECEx, ATEX, CSA and UL approvals for use in hazardous (classified) locations.

XCell Sensor Technology is MSA's platform of interchangeable, plug-and-play sensors used in the ALTAIR 5X. Sensor slots can be swapped without special tools so the instrument can be reconfigured for different gases. XCell sensors deliver an industry-first 60-second span calibration and sensor response/clear times under 15 seconds — up to 2× faster than the industry average (about half the time) — while using about half the calibration gas typically needed, driving typical cost savings of more than 50% on calibration gas, replacement sensors and maintenance.

The MSA ALTAIR 5X offers an industry-first 60-second span calibration and a 10-second bump test — and on the 10116927 that fast span calibration covers all five gases, including SO₂. This eliminates the extra calibration step SO₂ sensors normally require, saving calibration gas and time. Sensor response and clear times are under 15 seconds on LEL, O₂, CO, H₂S and SO₂ (up to 2× faster than the industry average), and calibration/bump testing can be automated with the MSA GALAXY GX2 Automated Test System and managed across a fleet with MSA Grid.

Yes. MSA states the ALTAIR 5X 10116927 meets or exceeds IECEx, ATEX, CSA and UL approvals, which are the international and North American schemes for intrinsically safe equipment used in hazardous (classified) locations where flammable gases or vapors may be present. This makes it appropriate for oil and gas, utilities, water/wastewater and industrial confined-space work. Operators must still be trained and follow the MSA user manual before use.

The MSA ALTAIR 5X 10116927 is an Industrial Kit that includes the ALTAIR 5X detector with a monochrome display, an internal integral pump, a 10-ft (3 m) sampling line and a 1-ft (305 mm) probe, configured for LEL, O₂, CO, H₂S and SO₂. It ships with free shipping from Industrial Safety Products. Note that gas meters are not eligible for returns or exchanges.

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, signaling that the wearer may be immobile — ideal for confined-space work where there is no direct line of sight. InstantAlert is a manually activated panic alarm the user can trigger to warn others of a hazardous situation. Both give workers additional ways to call for help.

The internal integral pump lets the ALTAIR 5X actively pull air samples through its 10-ft sampling line and 1-ft probe, so you can remotely test the atmosphere in a confined space before entering — something a diffusion (passive) detector can't do, since diffusion units only read the air immediately around them. On the 10116927 the pump has a recessed inlet that minimizes snag hazards and break points, and because it's integrated, the rugged over-molded housing acts as a pump-protecting shield rather than relying on a bulky snap-on attachment.

Yes, with the right sensor option. The ALTAIR 5X platform supports an integrated PID sensor for accurate VOC detection with programmable reference factors, and an infrared (IR) sensor option for gases such as CO₂ that are difficult to detect with electrochemical sensors. The IR option is also ideal for inert-gas sampling and environments with background sensor poisons (like silicones or lead compounds), letting one instrument platform cover standard gas detection plus VOC and specialty applications.

The MSA ALTAIR 5X 10116927 has a rugged over-molded polycarbonate housing, survives a 10-ft (3 m) drop test and carries third-party IP65 certification against dust and water ingress. MSA rates its XCell sensors for a 4-year expected sensor life on LEL, O₂, CO, H₂S, SO₂, NO₂ and IR sensors (3 years on NH₃ and Cl₂), backed by a standard 3-year instrument warranty, plus an industry-exclusive end-of-sensor-life warning so you can plan replacements before a sensor fails.

Both are ALTAIR 5X pumped kits with a 10-ft (3 m) sampling line and a 1-ft (305 mm) probe. The main differences are the display and the gas configuration: the 10116927 Industrial Kit has a monochrome display and a five-gas setup (LEL, O₂, CO, H₂S, SO₂), while the 10116928 Deluxe Kit has a color display and a four-gas setup (LEL, O₂, CO, H₂S). Choose the 10116927 if you need SO₂ monitoring out of the box; choose the 10116928 if you want the color display and don't need SO₂. Both use XCell sensors, monitor up to 6 gases, and can be expanded with additional sensor options.
