Helium Analyzer

[Deep Thought]

I just sent my Teledyne He/O2 analyzer into Teledyne HQ after the Truk Lagoon CCR trip, seems several people flooded the unit with sea water (flooded regulators).  One of the gals on the trip asked me "should this thing be smoking"?.....no I guess not to the tune of $450 in service and repair.

The Teledyne works well (when not flooded) but the drawback that I see is that the oxygen sensor is internal and the way I see it, you must flush it with a cal. gas -air- to verify the initial setting.  The knobs are sitting there just asking to be tweaked and this would affect your initial setting.

The Oxycrack analyzer works well - yes two separate units.

Things to consider:

battery powered, not requiring AC power seldom found on dive sites.

ease of calibration

g-whiz factor of how cool it looks.
