The fixed gas detector base AQ-FM S900 for AQ-sensor heads can communicate with a variety of hardware systems. The transmitter can also be used as switching relays with user-set values as a 4-20 mA gas transmitter and it can communicate with a network via the RS485 interface. Changing sensor heads is quick and easy, no configuration changes required. Calibration certificate included.
Attention! No AQ sensor head is included in the delivery, it must be ordered separately as an accessory!
