SS4128 (CO)

Electrochemical CO Sensor (0~1,000ppm)

DESCRIPTION

The SS4128 is an electrochemical sensor capable of accurately and consistently detecting carbon monoxide (CO) concentrations from 0 to 1,000 ppm. It features a linear output of 100 ± 30 nA/ppm, fast response time under 25 seconds (T90), and excellent repeatability for reliable performance. The sensor exhibits minimal cross-sensitivity to gases like hydrogen, nitrogen dioxide, and sulfur dioxide, ensuring precise measurements even in mixed gas environments. With a filter capacity exceeding 20,000 ppm-hour and a lifespan of over 24 months, the SS4128 is ideal for portable detectors, household CO alarms, industrial safety systems, and fire detection devices. Its robust design and wide operating range make it suitable for various safety applications.
