AST-14D Oxygen Sensor for Scuba Diving

AST-14D Oxygen Sensor for scuba diving, is a replacement to AP Diving Model APD14 O2 sensor. It fits in Inspiration, Evolution, XCCR and Flex rebreathers. It also replaces PSR-11-39-SMB O2 sensor. AST utilizes proprietary electrolyte formulation and super activated anode structure that ensures full utilization of Pb anode. This combination provides a longer sensor life without signal drift thus minimizing periodic calibration requirement. AST brand oxygen sensors are designed, developed and manufactured in the USA.
