GG-NH3-2%-EXP CTI Gas Sensor, Ammonia 0-2% (20,000 ppm), 4/20 mA output, explosion-proof enclosure

The GG-NH3-2%-EXP is designed to detect and monitor potentially explosive levels of ammonia vapors in the event of a catastrophic failure. Most codes specify an electrical shunt-trip at a level not higher than 25% LEL to remove potential ignition sources in the event of a serious ammonia leak. The GG-NH3- 2%-EXP allows for an earlier trip level of 12.5% LEL.Key Features:Ammonia selective catalytic bead sensor technologyUseful for activation of electrical shunt-trip or E-stop up to 20,000 ppmLow cost compared to infrared type ammonia sensorsIndustry standard linear 4/20 mA outputAbsolutely no zero drift compared to other catalytic bead type sensorsSensing element designed for long life in harsh industrial environmentsDesigned to perform in temperatures of -40°F to +150°FAccurately monitor explosive NH3 levels for emergency response situationsReal-time continuous monitoring2-year warranty, including replacement sensor element
