The Drager Polytron 2 XP Ex is an explosion-proof Gas Detector for continuous monitoring of combustible gases and vapors in ambient air. It converts the signal from a catalytic bead or IR sensor to a 4 to 20 mA analog or HART or RS 485 digital signal output.
The Polytron 2 XP Ex is designed for one-man calibration and offers a variety of diagnostics and self-test features. The configuration and calibration of the transmitter is menu guided and easy to perform.

Benefits:
Drager Sensor technology
Drager Polytron 2 XP Ex offers 2 sensing principles: catalytic combustion or infrared. The interior design of the catalytic bead sensor offers an extremely high sensitivity. Higher sensitivity also means shorter response times, higher accuracy and improved stability of the sensor signal.
Stand-alone system
With the 3 built-in relays, Draeger Polytron 2 XP explosion-proof Gas Detector can be used as an independent stand-alone unit. Two adjustable gas alarm levels and a fault alarm make it convenient to switch warning devices on-site, without having to run cables back and forth to a central controller. The sensor signal can still be transmitted using either the 4 to 20 mA, HART or RS 485 signal output.
