Product Overview
The EC4-1000-H2 is a hydrogen electrochemical sensor designed for measuring hydrogen gas concentrations. It offers a performance range of 0-1000 ppm with a maximum overload capacity of 2000 ppm. The sensor provides a sensitivity of 10-30 nA/ppm H2 and a zero in air at 20 C of less than 20 ppm H2. It features a resolution of 10 ppm H2 and operates linearly across its specified range. The response time (t90) is less than 70 seconds, and it exhibits a long-term output drift of less than 2% signal per month. This device is RoHS compliant.
