Nuvair O2 Quickstick Oxygen Analyzer Review

I was looking for an O2 analyzer that I could afford and didn't surprise my wife. This fit the bill. As others have pointed out, this is more than expected. I see that there is already a replacement sensor on the market for this product. I'm not sure when or if I'll need it, but I think it's good to know. Update after 6 months on performance.

Used on several diving trips. Some farms do not have analyzers, which reduces the risk to a minimum. I've been where they are on trips, but with 16 divers (like on a safari) I don't have to wait and hope my turn before diving.

After calibrating at 20.9% with a conventional air bottle on the valve port, I tested the bottle at 30%. Quickstick registered 36%. We tested with two other testers who registered 30%. Surprised, we put the 1st stage and the regulator on the EANx tank. Then I checked the controller with a quickstick…

First some context. After my Palm O2 showed 10-20% drift after 2-3 years of technical diving, it was obvious it was time to buy a new oxygen analyzer. At around $100 plus or minus, the Palm is very cheap, but you can't replace the sensor, which means you have to throw the thing away, and as an environmentalist, I hate breaking things that are 99% still good . Palm, this is just disgusting in 2021! I was thinking of a Divesoft analyzer that would protect me on ALL future dives that I, my…
