Model AST-17D Scuba Diving % O2 Sensor

AST-17D scuba diving % O2 sensor replaces Teledyne R-17D and R-17S, AII Model PSR-11-39-JD, Analox 9100-9212-94, IT Gambert D-01  MSA 406931, Vandagraph R-17VAN and City Technology CT-2 %O2 sensors. AST-17D %O2 sensor is a galvanic type micro fuel cell specific to oxygen. It is specifically designed for scuba diving. Electrical connection is a 3.5mm mono jack, external sensor casing has M16x1 thread front end. Expected sensor life is 42 months under ambient temperature and pressure. Proprietary electrolyte formulation and anode geometry ensure full utilization of Pb anode, thus providing longer life without signal drift and minimizing periodic calibration requirement. Sensor is designed, developed and manufactured in the USA.
