Analyzer He/O2 - Divesoft

Analyzer He/O2 is a precise apparatus for measuring oxygen helium concentrations in diving breathing gasses. It is a necessary tool for technical divers using nitrox and trimix mixtures.

The analyzer is characterized by its high accuracy and reliability thanks to an innovative solution for measuring helium concentrations. This technology works on the principle of measuring the speed of sound, thanks to which it is never necessary to replace the helium sensor.

Another quality of the Divesoft analyzer are its other functions and add-ins. Analyzers have an in-built calculator for mixing gases, it can be connected to a compressor for watching the oxygen concentration during a continuous filling with warning alarms (a relay can also be connected for automatic turning off of the compressor after surpassing critical values), and with the aid of measuring modules it is possible to measure electrical voltage and resistance. This is especially useful for finding out the state of the diving lights and scooters of for example of the state of a light bulb. The analyzer can identify some other gases and mixtures used for diving. In case of a hypoxic mixture without the presence of another inert gas other than nitrogen, it warns you not to breathe such gas through the text “FOUL AIR”. It can also identify argon and in special setting measure its purity (presence of air).
