OT-4XX — displayed oxygen monitoring
OT-4XX is the displayed O₂ transmitter in the EMS gas portfolio. Local indication helps check an oxygen concentration, but a life-safety deployment requires validated alarm thresholds, failure behavior, environmental suitability and independent approval of the whole system. Confirm the specific oxygen sensor technology, upper/lower measurable concentration limits, analog/current output code and pressure dependence in the ordered datasheet. The display does not establish hazardous-area certification or make it interchangeable with OT-3XX without wiring verification.
