Product Description
Product Overview
The SGX series of PS1 and PS4 Electrochemical gas sensors utilize a revolutionary Solid Polymer Electrolyte technology based on catalytic reaction. These sensors generate a very 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, and do not require power. The sensors exhibit very low cross-sensitivity to other gases and are available in models PS1-NO2-50 and PS4-NO2-50. Key applications include TLV Monitoring, environmental monitoring, and in parking garages.
