MaxO₂+A Scuba: professional nitrox analyser with replaceable Long Life sensor
For the nitrox diver who wants more than an entry-level model, the MaxO₂+A Scuba is the obvious choice. The patented ergonomic design sits comfortably in the hand and allows one-handed operation, even with diving gloves. The internal MAX-250+ galvanic Long Life sensor offers an expected life of more than 900.000 O₂% hours, at least 2 years in typical applications, and is replaceable when the sensor life has been reached.
The MaxO₂+A Scuba is a complete dive cylinder oxygen tester for use from the cylinder valve via the QuickOx adapter or from the low-pressure inflator hose via the BC adapter. With approx. 5.000 hours of battery life on 2 AA batteries, the analyser lasts for years without a battery change in normal diving use. The weekly calibration reminder ensures reliable measurements at all times.
When do you choose the MaxO₂+A over the Handi+ Scuba?
The MaxO₂+A is the right nitrox analyser when you dive intensively, want a replaceable sensor, need more battery life (5.000 vs. 1.850 hours) or require 24 months of sensor warranty. For recreational use on a limited budget, the Handi+ Scuba is the alternative. For remote measurement with an external sensor on a coiled cable, the MaxO₂+AE is the right version.
Applications
The MaxO₂+A Scuba is suitable for recreational and technical nitrox divers, dive professionals, dive schools with intensive use, dive boats and filling stations that need to verify O₂ percentage continuously.
