SGX Sensors PS4-O2-25%, Oxygen Gas Sensor IC for Air Quality Monitors

The SGX Sensors series of PS1 and PS4 Electrochemical gas sensors are using a revolutionary ’Solid Polymer Electrolyte’ technology that is based on the principle of catalytic reaction. The target gas to be measured generates a very small current, proportional to the gas concentration. Our technology offers a stable, high quality and cost-effective manufacturing process. The SGX solid polymer electrolyte gas sensors are available in a very small size, are highly sensitive, do not use power and have very low cross sensitivity from other gases.
