The SGX series of PS1 and PS4 Electrochemical gas sensors leverage 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. Designed for high sensitivity and low power consumption, they exhibit minimal cross-sensitivity to other gases and are available in a compact size. The PS1-O3-5 and PS4-O3-5 models are specifically designed for ozone detection.
