The GDX-350 transmitter with Smart Sensor technology provides accurate and continuous detection of toxic, combustible and asphyxiate gases using infrared, catalytic bead and electrochemical sensors. The full-featured design of the GDX-350 includes a large LCD display, a 4 to 20 mA interface, programmable alarms, optional relays and a Modbus interface. Exclusive, pre-calibrated replacement sensor technology simplifies maintenance requirements.

Its rugged construction, intrinsic safety capability (in two-wire mode with barrier) and an explosion-proof housing allow the GDX-350 to function in extreme temperature conditions like blast chillers and deep freezers. The GDX-350 can be placed directly in many classified or hazardous industrial environments to deliver reliable, superior sensing performance that protects personnel, equipment and property.
