SGX Solid Polymer Electrolyte Gas Sensors - Ozone (PS1-O3-5 & PS4-O3-5)
The SGX series of PS1 and PS4 Electrochemical gas sensors leverage 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. Designed for high sensitivity and low power consumption, they exhibit minimal cross-sensitivity to other gases and are available in a compact size. The PS1-O3-5 and PS4-O3-5 models are specifically designed for ozone detection.

Important Notes:
- Performance is based on conditions at 20°C, 50% RH and 1 atm, flow rate >150qcm/min, using SGX recommended circuitry.
- Sensor performance is temperature dependent; contact SGX for performance outside 20°C.
- Do not solder to connector pins to avoid damage and warranty invalidation.
- Recommended connector pin details are available in the SGX website's FAQ section.
- Avoid exposure to high concentrations of solvent vapors during storage, fitting, and operation.
- When using sensors on PCBs, use degreasing agents prior to fitting.
- For life safety applications, check sensor response to gas before use.
