Product Overview
The EC4-200-Cl2 Chlorine Electrochemical Sensor is designed for the detection of chlorine gas. It offers a performance range of 0-200 ppm with a sensitivity of 250-650 nA/ppm Cl2. This sensor is characterized by a low zero deviation across a wide temperature range (-20 to +40C) and a resolution of 0.1 ppm Cl2. It features a linear response across its operating range and a t90 response time of less than 30 seconds. The sensor has an expected lifetime of 2 years and is RoHS compliant. It operates at 0V applied potential and requires an external operating circuit as detailed in the Electrochemical Toxic Sensor Application Note.
