Nuvair O2 Quickstick Analyzer

O2 Quickstick Analyzer

The Nuvair O2 Quickstick is the first truly diver-friendly handheld oxygen analyzer designed for fast, reliable gas verification in the field. Rugged, compact, and remarkably affordable, it gives divers the confidence of verifying their own nitrox or oxygen mixes without relying on shared equipment.

Built with a sealed, water-resistant housing and anodized marine-grade aluminum body, the O2 Quickstick is nearly indestructible and perfectly suited for boats, fill stations, and travel kits. No hoses, adapters, or cables are required—just turn it on, calibrate, and analyze.

Whether you're analyzing nitrox at the dock or confirming oxygen content above water, the O2 Quickstick delivers professional-grade performance in a pocket-sized device.

Includes clear protective sleeve.
