Analytical Industries PSR-11-39-MD Oxygen Sensor AII PSR-11-39-MD The Analytical Industries PSR-11-39-MD Oxygen Sensor is the most commonly used '10 mV in Air' type in the scuba industry, popular in both rebreathers and analyzers. The PSR-11-39-MD, with a 3-pin Molex connector, is compatible with the Teledyne R-22D and Maxtec MAX-305F. This type of connector is used in the O2ptima, Prism2 (but not Explorer), KISS Classic/GEM and upgraded KISS Sport, Megalodon and Pathfinder, Hammerhead, Poseidon, rEvo, and many other brands of rebreathers. Specifications Connector: Molex Range: 0-100% Oxygen Signal Output: 8.5-13 mV Response 90%: 6 sec Expected Life: 42 months Warranty: 12 months
Analytical Industries PSR-11-39-MHD Oxygen Sensor AII PSR-11-39-MHD The PSR-11-39-MHD is a special version of the PSR-11-39-MD which provides a slightly higher mV range. Do not use the MHD version unless recommended by the rebreather OEM for your specific unit because otherwise some sensor validation checks may produce misleading results. Specifications Connector: Molex Range: 0-100% Oxygen Signal Output: 9-13 mV Response 90%: 6 sec Expected Life: 42 months Warranty: 12 months
