SRX-25F3 utilizes aqueous KOH electrolyte instead of acid electrolyte. Aqueous KOH electrolyte enhances the sensor’s performance in terms of accuracy, stability, repeatability and expected operating sensor life. This sensor ideal for inert gas streams but is not recommended for applications in gas streams containing CO2 gas. Proprietary electrolyte in combination with unique anode structure ensures full utilization of the anode and provides with excellent signal stability. and longer life without signal drift thus minimizes periodic calibration requirement. Sensor is designed, developed and manufactured in the USA.
