SS2128-B (CO)

Electrochemical CO Sensor (0~1,000ppm)

DESCRIPTION

SS2128_B is a 2-electrode electrochemical sensor designed to accurately detect carbon monoxide (CO) in the range of 0 to 1,000 ppm. It provides a linear output of 60 ± 20 nA/ppm, a fast T90 response time under 20 seconds, and a filter capacity exceeding 20,000 ppm-hour. With low cross-sensitivity to hydrogen, hydrogen sulfide, and nitrogen oxides, the sensor ensures reliable detection even in mixed gas environments. Its compact design and stable performance make it an ideal solution for small detectors, household CO alarms, and low-power devices.
