SS3128_B Carbon Monoxide Sensor

Miniature 2-Electrode Design for Ultra-Compact Devices

SS3128_B is a miniature 2-electrode electrochemical carbon monoxide sensor designed to detect CO concentrations from 0 to 1,000 ppm.
With an ultra-fast response time (T90 < 10 sec) and compact size, SS3128_B is ideal for applications where speed and space are critical.
The sensor delivers stable, linear output (60 ± 20 nA/ppm) and maintains excellent baseline stability over long-term operation.
Low cross-sensitivity to gases such as hydrogen (<20 ppm at 100 ppm H₂), NO, and H₂S ensures accurate CO detection even in mixed gas environments.
Designed for use in portable gas detectors, wearable safety monitors, and consumer safety devices, SS3128_B provides cost-effective and high-performance gas sensing.
