Divesoft He/O2 Analyser
Divesoft Analyser He/O2 is a precise analyser using speed of sound for measuring oxygen and helium concentrations in diving breathing gasses. It is a necessary tool for technical divers using nitrox and trimix mixtures and does not require Helium sensor replacement.
Dispatched in 1 to 2 days
The Divesoft He/O2 Analyser 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. Ever!
No more expensive Helium sensor changing... Ever!
Another quality of the Divesoft Analyser are its other functions and add-ins. Analysers 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).
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 batteries.
The analyser 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).
Analyser is charger through included USB 2.0 AB cable.
Simple flow limiter
EVA case for Analyzer He/O2
USB 2.0 "AB" cable
Sturdy and durable
Durable design supported by premium materials that will last.
Precise and accurate
Benchmark in accurate helium and oxygen analysis with single point calibration or three-point calibration for highest precision.
Divesoft He/O2 analyser does not use an electrochemical He sensor. It uses patented sensor to measure the speed of sound to determine the density of the measured gas mix. Which means no need for replacement and no additional expenses connected to He sensor replacement. Ever!
Speed of sound
Analyser He/O2 uses Divesoft's patented method of He content measurement based on speed of sound. That makes their analyser a true benchmark while allowing you to own the analyser without any addition cost with top of the line precision.
Rechargeable Li-Ion battery with USB charging. For your convenience as well as for purpose of continuous gas analysis.
Firmware designed to provide real time gas calculations for the most accurate cylinder labelling.
Easy access Oxygen cells
Uses Teledyne or Analytical Industries Oxygen cell.
Patented Helium content measurement
Characterised by its high accuracy and reliability thanks to an innovative solution for measuring helium concentrations. Working on the principle of measuring the speed of sound via the gas density and using microphones, it is never necessary to replace the helium sensor. He/O2 analyser is a precise tool for measuring oxygen helium concentrations in diving breathing gases.
Display & Sensors
OLED display with adjustable brightness makes reading gas analysis crystal clear, even in direct sunlight. Using barometric pressure sensor, analyser accommodates for atmospheric changes and compensates reading according to current conditions and altitude.
Every analyser has built in calculator for mixing gases. As well as a continuous mixing mode, for watching the oxygen and helium concentration with warning alarms, when the mixture falls out of preset limits.
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.
Gas mixing solver
Solver computes the procedure for mixing the required gas mix of up to three gases. It is possible to include the remaining mix in the bottle to be filled in the calculation. Simulator mode will compute mixture blended from up to four gases. You can enter mixtures either manually, or switch to measurement mode and measure directly the desired mixture.
