Product Overview
The EC4-50-ClO2 is an electrochemical sensor designed for the detection of Chlorine Dioxide (ClO2). It operates within a range of 0 to 50 ppm with a sensitivity of 220-580 nA/ppm ClO2. The sensor exhibits a zero point in air at 20 C of less than 0.09 ppm ClO2 and a resolution of 0.05 ppm ClO2. It is engineered for a linear response across its specified range and has a t90 response time of less than 60 seconds. The sensor has an expected lifetime of 2 years and a long-term output drift of less than 2% change in output per month. It requires an operating circuit as detailed in the Electrochemical Toxic Sensor Application Note and is designed to be RoHS compliant.
