BFT-44 Gas Detection Transmitter
Single/Dual Sensor Capable Transmitters

The new state of the art BFT-44 transmitter further builds upon the success of the earlier BFT-48 transmitter. This versatile unit has a vivid color display which changes color to match alarms states. The unit also has an embedded web page enabling an intuitive remote user interface. The web page is accessed through a standard Ethernet connection and allows the transmission of data over existing network infra-structure to our BFC-64 controller, smart phones, PC’s, and tablets.
