SS3128 Carbon Monoxide Sensor
Miniature Electrochemical Sensor for Portable Safety Devices
SS3128 is a miniature 3-electrode electrochemical CO sensor designed for measuring carbon monoxide in the range of 0 to 2,000 ppm.
It delivers a linear output of 70 ± 20 nA/ppm and a fast T90 response time of under 20 seconds, with low baseline drift and stable long-term performance.
Its compact form factor and high filter capacity (≥20,000 ppm-hours) make it ideal for use in space-constrained applications like wearable gas monitors, residential CO alarms, and handheld safety devices.
Low cross-sensitivity to hydrogen and other gases enhances reliability in mixed gas environments.
