Product Overview
The SGX series of PS1 and PS4 Electrochemical gas sensors utilize a revolutionary 'Solid Polymer Electrolyte' technology based on catalytic reaction principles. These sensors generate a small current proportional to the target gas concentration, offering a stable, high-quality, and cost-effective manufacturing process. They are characterized by their very small size, high sensitivity, no power consumption, and low cross-sensitivity to other gases. Key applications include general gas detection, consumer markets, VOC gas detection, mobile phone noses, indoor & outdoor air quality monitoring, and low-power nose applications.
