AT-4XX — ammonia with local display
AT-4XX is listed by EMS as a displayed ammonia transmitter, distinct from the non-displayed AT-3XX. The local reading may aid field checks, but the output scaling, measuring range and alarm design must follow the exact calibration and ordered code. Position the sensing portion near the intended airflow or likely leakage zone while keeping maintenance access and environmental temperature in view. A concentration display does not prove an intrinsically safe enclosure or independently certified life-safety function.
