Yes. The MSA ALTAIR io 6 (part 10255039) is well suited to confined space entry because it has a fully integrated sampling pump built into the instrument — unlike wearable detectors that need snap-on pump accessories — so you can draw and test the atmosphere inside a tank, vessel or manhole before anyone enters. This configuration detects five gases (combustible/LEL, O₂, CO, H₂S and SO₂) on a 6-gas capable platform, is approved for Class I, Division 1, Groups A–D (T4) hazardous locations, and adds out-of-box LTE-M cellular connectivity and GPS for real-time visibility of who is entering and where.

The MSA ALTAIR io 6 10255039 detects five gases in this configuration: combustible gas/LEL (0–100% LEL or 0–5% Vol CH₄, catalytic sensor), oxygen O₂ (0–30% Vol), carbon monoxide CO (0–2000 ppm), hydrogen sulfide H₂S (0–200 ppm) and sulfur dioxide SO₂ (0–20 ppm) — the O₂, CO, H₂S and SO₂ sensors are electrochemical. It is built on a 6-gas capable platform using MSA XCell sensors, so it can be reconfigured for additional gases.

Yes. The MSA ALTAIR io 6 10255039 meets or exceeds Class I, Division 1, Groups A, B, C and D, temperature code T4, over an operating range of -20 °C to +50 °C, and carries NA/IEC/ATEX approvals. That makes it appropriate for classified hazardous locations where flammable gases or vapors may be present, such as oil and gas, utilities and industrial confined-space work. Operators must still be trained and follow the MSA user manual before use.

The MSA Grid is MSA's cloud-based connected-safety platform for fleet management and worksite visibility. The ALTAIR io 6 connects to it out of the box using built-in LTE-M cellular connectivity — no local Wi-Fi, Bluetooth or network setup required. Device data (gas readings, alarms, device status and GPS location) streams automatically and securely to the cloud, where safety teams can view it in real time, push one-click configuration updates over the air, and manage compliance across the whole fleet.

MSA id™ is a digital device-assignment system built into the ALTAIR io 6 ecosystem, using an included MSA ID Tag. It lets safety managers effortlessly assign a detector to a specific worker and, combined with integrated GPS and secure cloud connectivity, know when, where and who is using each device in real time. Together with the MSA Grid it gives next-level visibility into a safety program — digital assignments, live location, and one-click over-the-air configuration.

The ALTAIR io 6 has a fully integrated pump built into the instrument so it can actively draw air samples for remote or pre-entry testing without adding external pump accessories. Unlike wearable diffusion detectors that rely on snap-on sampling attachments, the io 6's pump is part of the device, simplifying use on the job site, and it remains compatible with existing MSA sampling accessories (probes and sample lines). This makes it purpose-built for confined-space pre-entry sampling.

The MSA ALTAIR io 6 10255039 is built tough with an IP65 ingress-protection rating and a 10 ft (3 m) drop-test rating, designed to perform through full shifts in harsh conditions. It uses swappable sensors and batteries for quick change-outs during lengthy applications, which maximizes uptime, and its high-visibility black-and-white display and single-hand-operation grips make it easy to read and use on site.

The MSA ALTAIR io 6 uses a rechargeable Lithium Polymer battery that runs about 16 hours typical (13 hours when a PID sensor is fitted) and charges in roughly 6.5 hours at room temperature. It weighs just 0.9 lb (14.4 oz), operates from -4 °F to 122 °F (-20 °C to 50 °C), and its batteries are swappable for uninterrupted use across long or back-to-back shifts.

The MSA ALTAIR io 6 10255039 ships with calibration tubing, a charging cable, spare filters and an MSA ID Tag, and it ships free from Industrial Safety Products. It is a fully connected 6-gas capable detector configured for LEL, O₂, CO, H₂S and SO₂. Note that gas meters are not eligible for returns or exchanges.

MSA rates the ALTAIR io 6 sensors for long service life: the combustible/LEL catalytic sensor is rated for 5 years, and the electrochemical O₂, CO, H₂S and SO₂ sensors are each rated for 7 years. Because the sensors are swappable, an individual sensor can be replaced at end of life without retiring the whole instrument, helping maximize uptime and lower long-term cost of ownership.
