Handsets disagree on MV values

What comes new with an O2ptima ? What comes with a Hammer Head ?
AI recomends two types one with a higher out-put.

PSR-11-39-MD PSR-11-39-MD [] - $70.00 : CCRsense, Oxygen Sensors for Closed Circuit Rebreathers

PSR-11-39-MHD PSR-11-39-MHD [] - $70.00 : CCRsense, Oxygen Sensors for Closed Circuit Rebreathers

What is recomended ?

I have use r22ds and both AI cells.. the only difference in the MHD (for AI) is that it has a higher guaranteed low working voltage (9mv vs 8.5) so in theory the MHD is a better choice but either will work as long as you get 40mv in 100% oxygen. Teledyne cells are only guaranteed to be 7mv which would not work on a HH.. Most (but not all) teledyne's I have seen over the years have been at least 8.5mv
