Product Overview
The SGX series of PS1 and PS4 Solid Polymer Electrolyte gas sensors utilize revolutionary 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 manufacturing process. They are characterized by their very small size, high sensitivity, zero power consumption, and low cross-sensitivity to other gases. Ideal for applications in swimming pools, the chemical industry, portable and fixed-point monitoring, environmental monitoring, semiconductor manufacturing, water treatment, leak detection, and TLV-monitoring.
