The SGX series of PS1 and PS4 Solid Polymer Electrolyte Gas Sensors utilize a revolutionary technology based on catalytic reaction to measure hydrogen sulfide (H2S). These sensors generate a small current proportional to the gas concentration, offering a stable, high-quality, and cost-effective manufacturing process. Key advantages include a very small size, high sensitivity, no power consumption, and very low cross-sensitivity to other gases. They are designed for a wide range of applications including biogas, water treatment plants, leak detection, and portable & fixed point monitoring.
