PS4-PH3-20

PS4-PH3-20 SGX series PS4 solid polymer electrolyte gas sensor is 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. Key applications include TLV monitoring and parking garages.
