SS3128-B (CO)

Electrochemical CO Sensor (0~1,000ppm)

DESCRIPTION

SS3128-B is a miniature 2-electrode electrochemical CO sensor capable of accurately detecting carbon monoxide concentrations from 0 to 1,000 ppm. Featuring an ultra-fast response time (T90 < 10 sec) and compact design, it is ideal for portable detectors, wearable safety gear, and consumer CO alarms. It delivers a linear output of 60 ± 20 nA/ppm and maintains excellent baseline stability over extended use. Designed for low cross-sensitivity, it performs reliably even in mixed gas environments with hydrogen (H₂), NO, and H₂S.
