The MSA 10106722 is a genuine MSA XCell Ex replacement sensor that detects combustible gases (LEL) and methane. It is a catalytic-bead sensor with dual detector beads, measuring 0–100% LEL or 0–5% CH4, and it fits MSA ALTAIR 4X, 4XR, and 5X gas monitors. It is a single-gas (combustible) replacement sensor sold at Industrial Safety Products with free shipping.

The MSA 10106722 XCell Ex combustible/methane sensor fits the MSA ALTAIR 4X, ALTAIR 4XR, and ALTAIR 5X gas monitors. Confirm your instrument is one of these models before ordering, since it is a model-specific replacement sensor for the LEL/combustible channel.

The MSA 10106722 measures combustible gas from 0 to 100% LEL (1% LEL resolution) or methane from 0 to 5% by volume CH4 (0.05% Vol CH4 resolution). Its factory alarm setpoints range from a minimum of 5% LEL to a maximum of 60% LEL, and it operates over a -10 to 40 °C temperature range.

Very fast — the MSA 10106722 has a typical response time of t(90) under 15 seconds to pentane and under 10 seconds to methane, meaning it reaches 90% of the true reading in that time. This industry-leading response helps workers react quickly when a combustible atmosphere is present.

The MSA 10106722 has a typical life of more than 4 years thanks to its dual detector beads, which means fewer sensor replacements over the instrument's service life. It also carries a 3-year warranty. Its low power consumption lets an instrument run up to 3 shifts, and a robust filter keeps the sensor free of poisons and inhibitors for long-term reliability.

The MSA 10106722 is a catalytic-bead (pellistor) LEL sensor: it detects combustible gas by catalytically burning it on a heated bead, so it requires oxygen to work and reads combustibles as a percentage of the Lower Explosive Limit (LEL). Catalytic sensors can be degraded by "poisons" such as silicones, lead, and sulfur compounds. The 10106722 counters this with an extremely robust filter that helps keep the sensor free of poisons and inhibitors, extending its usable life.

Yes. The MSA 10106722 uses a patented support system built to survive a significant drop inside the instrument, and its dual-detector-bead design gives it a life of more than 4 years. Combined with a robust poison-resistant filter and low power draw (up to 3 shifts per charge), it is built for demanding industrial, oil & gas, and confined-space environments.

The MSA 10106722 combustible sensor has factory alarm setpoints ranging from a minimum of 5% LEL to a maximum of 60% LEL. This lets the ALTAIR 4X, 4XR, or 5X monitor warn workers well before a combustible atmosphere reaches a dangerous concentration, with the exact threshold configurable within that range.

Yes. The MSA 10106722 is a genuine MSA XCell Ex combustible gas and methane replacement sensor (SKU 10106722), available at Industrial Safety Products (industrialsafetyproducts.com) with free shipping. It is the correct LEL/combustible sensor for MSA ALTAIR 4X, 4XR, and 5X monitors and is backed by a 3-year warranty.

Yes. The MSA 10106722 detects methane (CH4) directly, reading it either as 0–100% LEL or as 0–5% by volume CH4 with 0.05% Vol resolution, and it responds to methane in under 10 seconds (t90). That makes it suitable for applications where methane is the target combustible gas, such as utilities, wastewater, mining, and confined-space entry with the ALTAIR 4X, 4XR, or 5X.
