GG-NH3-500-EXP CTI Gas Sensor Ammonia 0-500 PPM 4-20 mA Output, Explosion-proof Enclosure

The GG-NH3-EXP is designed for early leak detection of ammonia vapors in hazardous areas. Most codes specify audio visual alarms at 25 ppm and emergency ventilation at 150 ppm in the event of an ammonia leak. The GGNH3-250-EXP provides great accuracy at both of these levels.
