Divesoft Analyser He/O2 Stand Alone

  • Divesoft - DS-8313 Ask a Question

Divesoft Analyser He/O2 for measuring oxygen, nitrogen and helium concentration in diving breathing mixtures.

The Scuba Doctor use and throughly recommends this analyser. It is by far the best on the market today. We use them day in and day out in our store and totally punish them, they have never missed a beat.

This Stand Alone Divesoft Analyzer includes:

The Divesoft Analyzer He/O2 is accurate and precision apparatus for measuring oxygen, nitrogen and helium concentration in diving breathing mixtures. It is a necessary assistant for technical divers who use nitrox and trimix mixtures.

The Divesoft He/O2 Analyser is characterized by high precision and reliability through innovative solutions of helium content measurement. This technology works on the principle of the speed of sound and is developed and patented by Divesoft. Because it is never a need to change the helium sensor, as is the case with other analyzers.

Another advantage of the Divesoft Analyzer He/O2 is the number of features and accessories. Analysers have built-in calculator for mixing gases, it can be connected to the compressor to monitor oxygen concentration during continuous filling with warning alarms (can also be wired relay automatically turns off the compressor when critical values), and plug-in modules can measure voltage and resistance. This is especially useful for determining the state of charge of diving lamps and scooters respectively state bulbs / lamps.

The Divesoft Analyzer He/O2 can detect a faulty air if it is a hypoxic mixture with nitrogen and other inert gas is not present. This feature represents a major safety advantage over other analyzers in the world market.

How It Works?
Standard electrochemical oxygen sensor is used for oxygen content measurement. The content of helium is measured by speed of sound. Each gas has different spread of sound because his density. The device generates sounds (knocking) and they go thru labyrinth and there are caught with sensitive microphone. The accuracy is +/- 1%.

How To Use?
The Divesoft He/O2 Analyzer has many sophisticated features, nevertheless control is easy and intuitive. Mount one of flow limiters on valve, switch the analyzer on and oxygen and helium content appears.

Tech Tip

Trust No One

Get an analyser. Learn how to use it properly. Calibrate it before every use. The only person who should be analysing your cylinders is you. The only analyser you should use is yours.

Label Everything

Clearly label anything that isn't air. If the MOD is less than the maximum possible depth of the dive (think deco cylinders), make sure the MOD stands out where not only you can see it, so can your buddies. Make it obvious to everyone if you are using the wrong cylinder at the wrong depth.

Consider putting a small piece of tape on each second stage, just in front of the mouthpiece, that has the MOD for the cylinder it is attached to. (This is in addition to the standard cylinder markings.) Any little thing that may save your life helps.
