Nuvair products

The Nuvair Pro O₂ Handheld Analyzer measures oxygen levels in mixed gases from 1% to 100% oxygen. It comes with a water- and impact-resistant case and is available in three power options: Wall plug-in, 9-volt or rechargeable lithium battery. The oxygen sensor and batteries are user-replaceable. Easy-to-operate, extremely accurate and stable, the Nuvair Pro O2 is preferred by commercial, military, technical and advanced recreational divers using nitrox. Our water- and impact-resistant case is designed for everyday use in the marine environment. The Pro O2 is also popular with medical, welding, and other industries not related to diving. To change the battery or sensor, simply remove four screws to have easy access to these user-changeable components. The Nuvair Pro O2 Analyzer can be placed in-line with your compressor during mixed-gas production or used as a standalone unit for testing mixed gas and nitrox individual scuba tanks or storage cylinders. 

The handheld Nuvair Pro O₂ Alarm Analyzer is easy to operate and rugged. Users can set two audible/visible alarms for high and low oxygen percentages. When the alarm sounds, the analog output can activate an optional relay that automatically shuts down compressors, sounds an alarm, or activates a back-up system. Easy to operate, extremely accurate and stable, the handheld Nuvair Pro O2 Alarm Analyzer is preferred by commercial, military, technical and advanced recreational divers using nitrox and non-divers who require a simple oxygen analysis of compressed gas or contained spaces. Audible and visual alarms for low and high oxygen content can be set by the user. If the alarm sounds, the analog output can activate an optional relay that shuts down compressors automatically, sounds a remote alarm, or activates an emergency backup system. Price varies according to power options.

With a maximum operating pressure of 5000 psi (345 bar), Coltri Compact Nitrogen Boosters compress and purify nitrogen gas. Available with a 5.5 or 7.5 hp electric motor that delivers 7-9.4 CFM (200-265 L/min). A booster compressor receives gas under pressure and is therefore more efficient and pumps more gas per horsepower than a standard compressor. Charging rate is variable and is based upon intake pressure that can vary between 29-73 psi (2-8 bar). A nitrogen booster is equipped with a service stage to recover nitrogen blowby from the crankcase. The booster units are vented at each start-up to remove the nitrogen amount which eventually has been contaminated during booster standby.

With a working pressure of up to 6000 psi (413 bar), the Coltri Silenced Nitrogen Booster is based on the successful MCH22-36 pump platform.
