The LBW-WATCHMAN Ammonia Leak Detector from Cool
Air Incorporated has all the features you need to protect your
personnel and product. It has a solid-state, long-life ammonia
sensor cell that provides fast and accurate detection of
ammonia gas. The sensor cell will not deplete during an
ammonia leak, from background ammonia vapors, or
during testing &/or calibration.
The front panel display indicates ammonia concentration in
parts per million (PPM). The detector has a 4-20 mA analog
output for PPM that will seamlessly integrate with your existing
automation system.
To reduce nuisance alarms during cleaning, servicing, testing,
and/or calibration, the LBW-420 has a service mode that
temporarily disables the detector’s 4-20 mA signal. To further
