Ammonia Leak Detector

Cool Air Inc.'s Model LBW-420 displays ammonia concentration and alarm status, and its early warning system allows you to react before ammonia levels reach full alarm status. The detector has a 4 to 20 mA analog output for integrating with existing facility systems. To reduce nuisance alarms, the device has a service mode that temporarily disables its relays during service and testing. It also operates as a smoke detector.
