| Operating Temperature | -20℃~+55℃ | Description | Gas Sensor RoHS |
| Mfr. Part # | PS4-O2-25% | Model Number | PS4-O2-25% |
The SGX series of PS1 and PS4 Electrochemical gas sensors utilize 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 manufacturing process. They are characterized by their very small size, high sensitivity, zero power consumption, and low cross-sensitivity to other gases. Ideal for medical, industrial, combustion control, food industry, and general gas detection applications.
