SS1118 (O₂)

Galvanic Cell(lead-oxygen battery) O₂ Sensor (0~100%)

SS1118 is a galvanic-type oxygen sensor designed to measure oxygen concentrations from 0 to 100% by volume. Delivers stable, linear output signal with rapid response time and excellent accuracy, ideal for portable instruments, safety monitoring, combustion analysis, and medical applications.
Built-in temperature compensation minimizes drift across varying environments. Typical lifespan exceeds 24 months in air with minimal cross-interference, ensuring reliable performance under wide ambient conditions.

KEY FEATURES
    • Galvanic cell (lead-oxygen battery)
    • Measurement range: 0–100% Vol. O₂
    • Fast response time (T90 < 15 sec)
    • Accuracy: ±1% Full Scale
    • Long operating life (≥24 months in air)
    • Excellent linearity and low cross-interference
