SS3128-LH (CO)

Electrochemical CO Sensor (0~1,000ppm)

DESCRIPTION

The SS3128_LH is a miniature electrochemical CO sensor designed for accurate detection in hydrogen-containing environments. It offers minimal hydrogen cross-sensitivity (<10 ppm @ 100 ppm H₂), ensuring precise readings without false alarms. With a linear output of 60 ± 20 nA/ppm and a rapid T90 response time of under 10 seconds, this sensor is ideal for use in portable gas detectors, fire alarms, and residential CO monitors. Its compact 3-electrode design allows easy integration, and excellent selectivity against gases like H₂S, NO, and SO₂ ensures reliable performance in mixed gas environments.
