Our Products

Nuvair manufactures gas analyzers for diving, medical, public safety, industrial, government, and military use. Our analyzers are portable, rugged, accurate and easy to operate with user-changeable batteries and sensors. Analyzer configurations include handheld, panel mount, remote handheld, remote panel mount, and water-resistant enclosure.

Analyzers can evaluate single or multiple gases including oxygen (O2), nitrogen (N2), carbon monoxide (CO), carbon dioxide (CO2), and helium (He). For the technical diver, we offer several multigas analyzers. And for the diver who is looking for complete gas analysis, we manufacture the Pro 4 Warn, which analyzes O2, CO, CO2 and moisture.

PLEASE NOTE: Never expose gas sensors to pressure or you may cause damage and/or false readings. Damaged sensors will not provide accurate gas analysis. Inaccurate gas analysis can lead to serious personal injury or death. Most gas analyzers can be used to analyze a regulated gas sample flow, the contents of a gas cylinder, or the flow from a regulator. The flow rate of gas must equal 1-5 L/min. To produce this flow, a Flow Restrictor and Regulator may be required.

Oxygen

The Nuvair line of oxygen analyzing units come in a variety of styles to meet most applications and user requirements. Now available with audible and visible alarms. Other options include remote monitoring, relay ability and alarm outputs.

Make sure to check out the Nuvair O2 Quickstick, our top-selling oxygen analyzer for nitrox divers.

Carbon Monoxide

Odorless, tasteless and invisible, carbon monoxide can prove lethal to divers in small quantities. Available for personal use or for integration into a compressor system, CO analyzer options include audible alarms for low pressure, high temperature or CO detection.

Nitrogen

Our nitrogen analyzers are portable and easy to operate with user-changeable components. Used extensively in the automotive, food, and military industries. Available in handheld and panel mount versions.

Flow Restrictors & Meters

Flow restrictors optimize gas flow for accurate sampling with gas analyzers. Exposing analyzer sensors to non-optimum flow/pressure may cause sensor damage. Flow meters provide users a visual indicator of flow rate for accurate pressure delivery to sensitive gas sensors.

Products

Carbon Dioxide

We manufacture and distribute carbon dioxide analyzers for use with breathing gas mixtures and air. Handheld, panel mount and waterproof box with external relay are available options.

Helium

Designed for use with mixed gases, our helium analyzers come as handheld units or for compressor panel mounting. Compatible with heliox or trimix, our analyzers can continuously monitor helium content during gas mixing. Available in a waterproof box mount. 

Multigas

Designed for technical and rebreather divers, the Nuvair line of multigas analyzers are mounted in protective waterproof carrying cases. Analyzers are self-calibrating and include audible and visual alarms for user-defined set points.

Sensors & Batteries

We carry replacement carbon monoxide (CO) and oxygen (O2) sensors and batteries for all current and legacy gas analyzers manufactured and sold by Nuvair.
