SS2128-LH (CO)

Electrochemical CO Sensor (0~1,000ppm)

DESCRIPTION

SS2128_LH is a 3-electrode electrochemical carbon monoxide sensor designed for accurate CO detection in environments where hydrogen is present. It measures CO concentrations from 0 to 1,000 ppm and maintains cross-sensitivity to hydrogen below 10 ppm even when exposed to 100 ppm H₂. With a fast response time of less than 20 seconds (T90) and a filter capacity exceeding 20,000 ppm-hour, it provides stable performance for various safety applications. Its low cross-interference to gases such as H₂S, NO, and SO₂ makes it suitable for use in mixed gas environments requiring precise CO detection.
