Handi+ Scuba: portable nitrox analyser for testing dive cylinder oxygen
Nitrox diving requires you to know the exact oxygen percentage in your dive cylinder before every dive. The right gas mix determines your maximum safe depth and decompression planning. With the Handi+ Scuba you always have a reliable nitrox analyser at hand, ready to use on the jetty, the dive boat or at the filling station.
The Handi+ Scuba works as a dive cylinder oxygen tester via the OxyKnob adapter on the cylinder valve, or as an O₂ analyser on the BC inflator hose via the BC adapter. Measurement takes less than 15 seconds. The protective overmould protects the analyser in the rough diving environment. The non-replaceable MAX-250 galvanic sensor with temperature compensation guarantees reliable measurement throughout its entire life.
When do you choose the Handi+ Scuba?
The Handi+ Scuba is the most affordable nitrox analyser in the Maxtec scuba line. It is ideally suited for nitrox divers who want a reliable oxygen analyser for diving without the higher investment of the MaxO₂+ series. The sensor is not replaceable, which keeps the purchase price down. For intensive use or commercial applications, the MaxO₂+A or MaxO₂+AE with replaceable Long Life sensor is the better choice.
Applications
The Handi+ Scuba is suitable for recreational and technical nitrox divers, dive schools teaching students nitrox analysis, and dive boats and filling stations that want to check filled cylinders. The analyser is not suitable for use in potentially explosive environments or with flammable gases.
