Yes. The MSA Altair io 4 (part 10245598) is a rugged, connected wearable 4-gas detector built for confined space, turnarounds and plant maintenance, and emergency response. It continuously monitors the four most common atmospheric hazards — combustible gas/LEL, oxygen (O₂), carbon monoxide (CO) and hydrogen sulfide (H₂S) — using MSA XCell sensors, and is approved for Class I, Division 1, Groups A–D (T4) hazardous locations. What sets it apart from a basic detector is fully integrated LTE-M cellular connectivity plus GPS, so gas readings, alarms and worker location stream to the MSA Grid cloud in real time — giving safety teams live visibility across worksites from day one.

The MSA Altair io 4 10245598 detects four gases: combustible gas/LEL (0–100 % LEL, catalytic sensor), oxygen O₂ (0–30 % Vol), carbon monoxide CO (0–1999 ppm) and hydrogen sulfide H₂S (0–199 ppm). The O₂, CO and H₂S sensors are electrochemical. Sensor resolution is 1 % LEL, 0.1 % Vol O₂, 1 ppm CO and 1 ppm H₂S. It is built on MSA's XCell sensor platform, which supports 1-to-4-gas configurations and optional sensors such as methane, low-concentration H₂S, and hydrogen-resistant CO.

Yes. The MSA Altair io 4 10245598 is approved for Class I, Division 1, Groups A, B, C and D, temperature code T4 (-20 °C to +55 °C), and also carries Class I, Zone 0, AEx da ia IIC Ga T4 marking, plus FCC and Industry Canada approvals. That makes it suitable for classified hazardous locations where flammable gases or vapors may be present, such as oil & gas, utilities, mining and industrial confined-space work. Operators must still be trained and follow the MSA user manual before use.

The MSA Altair io 4 10245598 has fully integrated LTE-M cellular connectivity with 2G fallback, so it streams gas readings, alarms, device status and GPS location to the cloud-based MSA Grid automatically — no Wi-Fi or local network setup required. Supported carriers are the AT&T Global Partner Network and Verizon (USA only), and the device includes one year of basic subscription. Importantly, no subscription is required to use the device as a gas detector; the subscription enables the connected fleet-management features. It also keeps a minimum of 90 days of cloud-synced data logs.

The MSA Altair io 4 10245598 has built-in location awareness using concurrent GNSS (GPS and GLONASS), with GPS accuracy of about 8 ft (2.5 m). Location is updated every 30 seconds when a position is acquired; when no position is available the device searches every five minutes to conserve battery. Combined with its LTE-M cellular link and an RFID reader for MSA id device assignment, this lets safety teams see who is using each detector and where in real time — valuable for lone-worker safety and emergency response.

The MSA Altair io 4 10245598 uses a 2 Ah rechargeable battery rated for about 17 hours typical run time on LTE-M (16 hours on 2G), enough for a full shift plus margin. A full charge takes roughly 4.5 hours at room temperature, with a charging temperature range of 0–40 °C (32–104 °F). Actual run time varies with cellular and GPS coverage, ambient temperature, alarm activity and usage.

The MSA Altair io 4 10245598 is built for harsh industrial environments. It carries a dust- and waterproof IP68 rating (submersible to 2 m for 1 hour), exceeds 26 drops from 4 ft (1.2 m) per MIL-STD-810G 516.6 transit drop, is capable of surviving an incidental 25 ft (7.5 m) drop onto concrete, and withstands 60 minutes in the NFPA 1982-2018 tumble tester. It weighs just 9 oz (261 g) and measures 4.6 × 3.1 × 1.5 in (11.7 × 7.8 × 3.9 cm) in a rugged polycarbonate housing.

MSA rates the Altair io 4 10245598 sensors for long service life: the combustible/LEL catalytic sensor is rated for about 5 years typical, and the electrochemical O₂, CO and H₂S sensors are each rated for about 7 years typical. Actual sensor life can vary with environmental conditions and, for the combustible sensor, exposure to sensor poisons. The io 4 uses MSA XCell sensor technology, known for fast response and long life.

The main difference is connectivity. A traditional 4-gas monitor detects gas and alarms locally, but the MSA Altair io 4 10245598 is a fully connected wearable: built-in LTE-M cellular (with 2G fallback), concurrent GPS/GLONASS location, an RFID reader for MSA id digital device assignment, and automatic streaming to the MSA Grid cloud. That means real-time visibility of readings, alarms and worker location across worksites from day one, plus over-the-air fleet management and a minimum of 90 days of cloud-synced data logs — all in an IP68, Class I Div 1 rugged package that still works as a standalone detector without a subscription.

The MSA Altair io 4 10245598 (LEL, O2, CO, H2S) is available from Industrial Safety Products (industrialsafetyproducts.com) with free shipping. It ships in a 4-gas configuration with MSA XCell sensors, LTE-M cellular connectivity and a one-year basic subscription included. Note that gas meters are not eligible for returns or exchanges, so confirm the configuration you need before ordering.
