SGX Solid Polymer Electrolyte Hydrogen Sensors (PS1 & PS4 Series)
Product Overview
The SGX PS1 and PS4 series of hydrogen sensors utilize revolutionary Solid Polymer Electrolyte (SPE) technology, operating on the principle of catalytic reaction. These sensors generate a small current proportional to the target gas concentration, offering a stable, high-quality, and cost-effective manufacturing process. Designed for exceptional performance, they are compact, highly sensitive, power-free, and exhibit very low cross-sensitivity to other gases. Ideal for ambient monitoring, sensitive leak detection, battery production, semiconductor manufacturing, data center protection, and propellant detection.
