MSA ALTAIR io 6 in use

Mallory is Your Source for MSA Safety Gas Detection and CBRN Respiratory Protection

MSA Safety has built safety equipment since 1914, when two rescue engineers set out to stop underground explosions from killing miners. That same engineering focus now shows up in the gear tactical units, Hazmat response teams, and police officers carry into chemical and unknown-atmosphere environments. Departments that need to detect what they can’t see and breathe safely when they can, turn to MSA Safety for both.

Police departments in all 50 states have worked with Mallory for over 45 years. We're in this business because we care about people going home safe at the end of a shift, and our dedicated Public Safety Team brings that mindset to every piece of MSA Safety gear we help them select.

ALTAIR io™ 6 Multigas Detector

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 device allows fast, infrastructure-free unit assignment.

Built-In Operational Convenience

The high-visibility display and single-hand grip let an officer 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.

Millennium Gas Mask

Respiratory Protection for Civil Unrest and CBRN Response

The Millennium Gas Mask meets NIOSH’s CBRN Standard, giving officers a certified, tested response to chemical, biological, radiological, and nuclear threats. A NIOSH-approved CBRN canister protects against a minimum of 139 identified agents across seven families, including acid gases, hydrides, and particulates.

Comfort, Fit, and Dual-Side Weapon Sighting

Comfort and function are built into the design rather than added on. The six-point head harness allows easy donning, adjustment, and removal without pulling hair. The flexible, one-piece polyurethane lens eliminates the pressure points officers get from rigid lenses during extended wear. Canister inlet ports on either side let an officer sight and fire a weapon from either shoulder.

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.
