Mallory is Your Trusted Source for MSA Safety Fireground Gas Detection, Calibration, and Service

Emergency response crews face dangerous environment where they worry if the air fit to breathe, and is it going to explode? MSA’s ALTAIR io line addresses both, streaming real-time readings to the MSA Grid, so incident commanders see who’s exposed to what as it happens. Fire departments and rescue squads in all 50 states have trusted Mallory for 45 years. Getting people home safe is why we show up every day, and our Public Safety Team carries that commitment forward, knowing MSA gear inside and out.

Look to us to keep your detector fleet field-ready. Our MSA-certified technicians can calibrate and repair gas detection equipment in-house or at any of our 10 service centers nationwide.

Outstanding Simplicity and Powerful Sampling Capabilities

The ALTAIR io 6 samples an environment before anyone walks into it. Its built-in pump handles confined spaces and unknown environments, and it clips on to be worn between sampling points instead of carried by hand.

LTE-M cellular connectivity links the unit to MSA Grid software out of the box, giving real-time visibility into device location, status, and fleet compliance through integrated GPS. MSA id allows fast, infrastructure-free unit assignment.

Built-In Operational Convenience

The high-visibility display and single-hand grip let a firefighter read results and operate the unit one-handed. Swappable sensors and batteries mean fast turnaround during extended incidents instead of pulling the unit from service.

Continuous Monitoring That Deploys in Seconds

The ALTAIR io 4 is MSA’s wearable, continuously worn gas detector, built for crews
who need constant atmospheric monitoring throughout an incident. It connects automatically over cellular the moment it’s powered on. No IT setup, no manual pairing. A detector can go from the charging dock to a firefighter’s turnout gear
in seconds.

Built to Take a Fireground Beating

Fire and hazmat crews work in atmospheres that punish equipment, and MSA built the io 4 for it. The IP68-rated housing survives an incidental 25-foot drop onto concrete, more than two dozen 4-foot drops under MIL-STD-810G, and the same 60-minute NFPA 1982-2018 tumble test required of firefighter PASS devices.

Frequently Asked Questions

Can Mallory help us choose the right sensor configurations?

Yes. A wide range of interchangeable sensors is available, and the right combination depends on what your personnel encounter in the field. Our team works with you to help you match sensor selection to your mission before the order is placed.

What happens if a monitor needs calibration or repair after we buy it?

We service what we sell. Your department has a direct line to our team for calibration, repair, and troubleshooting rather than routing every issue back through the manufacturer.

What is a photoionization detector (PID)?

A PID relies on ionization as its basis of detection. When sampled gas absorbs energy from the detector’s UV lamp, the gas becomes excited and its molecular structure changes. The compound loses an electron and becomes a positively charged ion, at which point it’s considered ionized.

What is OMNIA Partners and how could it simplify our purchasing process?

OMNIA Partners is a cooperative purchasing organization. It runs competitively solicited, publicly awarded contracts on behalf of a lead public agency, and then makes those contracts available to other government agencies nationwide who want to compliantly “piggyback” onto them to procure efficiently and meet tight grant deadlines.
