SS2118 (O₂)

Galvanic Cell (Lead-Oxygen Battery) O₂ Sensor (0–25%)

DESCRIPTION

SS2118 is a galvanic-type oxygen sensor designed for accurate measurement of oxygen concentrations from 0 to 25% by volume. It provides a linear analog output, fast T90 response time of under 15 seconds, and excellent stability. Its compact form factor makes it ideal for use in portable instruments, industrial safety equipment, and combustion analyzers. The sensor operates reliably over a wide range of temperatures and humidity, with a typical operating life of more than 24 months in ambient air.
