Product Overview
The EC4-100-ETO is an Ethylene Oxide Electrochemical Sensor designed for performance measurement using Carbon Monoxide. It offers a measurement range of 0-100 ppm with a sensitivity of 440-1080 nA/ppm. This sensor features a fast response time (t90 <45 s) and low long-term output drift (<2% signal/month). It is suitable for operation within a temperature range of -20 to +50 C and humidity of 15-90% RH (non-condensing). The device is RoHS compliant and comes with a 2-year warranty. Calibration should be performed with the actual gas at a known concentration.
