The City Technology Oxygen CiTiceL is a premium electrochemical gas sensor engineered for the precise detection and continuous monitoring of oxygen (O2) concentrations. Built with a durable cylindrical white plastic housing, it features an advanced gas-diffusion membrane that facilitates optimal gas exchange for rapid and accurate readings. The sensor is designed for secure and straightforward integration, utilizing a metal terminal face with contact pins, a convenient red pull-tab, and a PCB-mount base equipped with concentric ring contacts and solder terminals (base board marked TGS/3). Manufactured in England under strict quality standards, this reliable O2 sensor is highly suitable for industrial safety applications, emissions monitoring, and portable gas detection instrumentation. For optimal longevity and performance, it is strictly advised to store the sensor in a cool place prior to deployment.
