Gas Analyzers

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 types of multigas analyzers including the Pro Trio, Pro He-O2, and Pro Trimix. For the advanced diver who is looking for complete gas analysis, we manufacture the Pro 4 Warn, which tests for O2, CO, CO2 and moisture (H2O).

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.
