PS4-NH3-100

PS4-NH3-100 SGX series ammonia gas sensor. This PS4 electrochemical 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 coal mines, general gas detection, industrial, plating, and storage room.
