The SS2128 is a high-performance electrochemical sensor designed for precise measurement of carbon monoxide (CO) concentrations from 0 to 2,000 ppm. It features a linear output of 70 ± 20 nA/ppm, a fast T90 response time of less than 25 seconds, and excellent repeatability. With over 20,000 ppm-hour filter capacity and low cross-sensitivity, it delivers reliable performance even in complex environments. Ideal for industrial gas detectors, residential alarms, and fire safety systems requiring high-concentration CO detection.
