The Chillgard 5000 Ammonia Monitor accurately detects ammonia gas leaks as low as 10 ppm for early notification, keeping your plant safe according to ANSI/IIAR and EN 378. Using Photoacoustic Infrared (PAIR) technology provides a more accurate measurement and requires less maintenance than traditional electrochemical gas sensors for lower cost of ownership.
