Model AST-17D Scuba Diving O2 Sensor

Model AST-17D scuba diving O2 sensor, replaces Teledyne R-17S, R-17d, AII Model PSR-11-39-JD, IT Gambert D-01  MSA 406931, Vandagraph R-17VANand City MOX-2 sensors. AST-17D is a galvanic type micro fuel cell specific to oxygen. It is specifically designed for scuba diving. Electrical connection 3.5mm mono jack, M16x1 thread front, expected sensor life 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.
