SS2178 (H₂)

Electrochemical H₂ Sensor (0~1,000ppm)

DESCRIPTION

The SS2178 is an electrochemical hydrogen (H₂) sensor capable of accurately measuring concentrations from 0 to 1,000 ppm. It features a linear output of 30 ± 10 nA/ppm, a fast T90 response time of under 30 seconds, and high sensitivity with a resolution below 2 ppm. The sensor offers low cross-sensitivity to gases such as CO, SO₂, H₂S, and NO, and maintains stable performance with a drift of less than 5% per year. Ideal for use in petrochemical plants, hydrogen storage facilities, refineries, and both fixed and portable gas detectors.
