Model SRZ-CF25

SRZ-CF25 Oxygen Sensor replaces Figaro Model KE-25 oxygen sensor. It is a galvanic type micro fuel cell and is specific to oxygen. Specifically designed for % O2 analysis in gas streams containing any level of CO2 gas; acidic electrolyte formulation used in the sensor makes it compatible with CO2 and other acid gases. It offers longer life without signal drift and minimizes periodic calibration requirement. AST brand sensors are designed, developed and manufactured in the USA
