AST-22D diving oxygen sensor – Replaces Teledyne R22, R22S and R24 Oxygen Sensors

AST-22D diving oxygen sensor replaces Teledyne R-22S, R22 and R24 oxygen sensors. AST-22D also replaces AII Model PSR-11-39-MD, City MOX-1 and MAX-12 diving oxygen sensors. This sensor fits in these KISS, Interspace Megalodon, Oxy Spy, Oxy2, Optima, Hollis Prism and Poseidon Rebreathers. Supper activated anode material along with proprietary electrolyte formulation ensures full utilization of Pb anode. This combination provides much longer sensor life without significant signal drift thus minimizing periodic calibration requirement. Sensor is designed, developed and manufactured in the USA
