Mfr. Part #:
PS1-SO2-50
Key Attributes
Model Number:
PS1-SO2-50
Product Description
Product Overview
The SGX series of PS1 and PS4 Sulfur Dioxide (SO2) 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 solution. Designed for small size and high sensitivity, they operate without power and exhibit low cross-sensitivity to other gases. Key applications include TLV Monitoring, the Steel Industry, Emission Monitoring, and the Oil & Petrochemical Industry.
