Divesoft HE/O2 Analyzer Set - Blender Standard
The Divesoft He/O2 Analyzer is a precise apparatus for blending and measuring oxygen helium concentrations in diving breathing gasses. It is an 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. 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).
This analyzer uses the standard R-22 style (3-pin Molex) replacement Oxygen sensor. It does ship to you with sensor installed and ready for use.

Customer Reviews
R-22 Oxygen Sensors - 'D' type vs 'S' type
The R-22 oxygen sensors are all characterized by the same physical dimensions, electrical characteristics and 3-pin Molex connector. The primary difference between the "S" type sensor and the "D" type sensor is the presence of a hydrophobic membrane on the face of the diving grade sensor. The membrane improves resistance to moisture, but slows the response of the sensor to changes in oxygen partial pressures by several seconds.
In practice, for use in diving gas analyzer applications the slightly slower response time of diving grade sensors is little consequence with the benefit being the design is more resistant to moisture found on the face of tank valves. If the diver or fill station operator fails to wipe or blow away any moisture present on the valve outlet, that moisture can enter the stream of gas being analyzed and affect the accuracy of the analysis.
Some prefer to use the D type sensors even in analyzers because of their resistance to moisture, others prefer the S type sensors for their slightly faster response time in analyzers - especially in frequent use applications.
Dive Gear Express offers both types:
- Analytical Industries brand ADI-PSR-11-39-MD (R-22D type diving grade)
- Analytical Industries brand ADI-PSR-11-39-MNB (R-22S type for analyzers only)
- Divesoft brand DS-3001 (R-22S type for analyzers only)
- Mares rEvo brand CR22D (R-22D type diving grade)
- Poseidon brand 6010-206 (R-22D type diving grade)
Both types will work in gas analyzers but the S type must never be used in rebreathers.
