SS4128 Carbon Monoxide Sensor

Reliable Detection for Industrial and Residential Safety

SS4128 is an electrochemical carbon monoxide sensor designed to detect CO concentrations from 0 to 1,000 ppm with high accuracy and consistency.
It delivers a stable linear output of 100 ± 30 nA/ppm and features fast response (T90 < 25 sec), high repeatability, and excellent baseline stability.
Cross-sensitivity to interfering gases such as H₂, SO₂, and NO₂ is minimal, ensuring reliable performance even in complex environments.
With a long operating life of over 24 months and a high-capacity filter (>20,000 ppm-hours), SS4128 is ideal for use in portable detectors, residential CO alarms, industrial safety systems, and fire alarms.
Robust design and wide environmental tolerance make it suitable for demanding safety-critical applications.
